ccedcb3648 interconnect: qcom: bcm-voter: Improve enable_mask handling
[ Upstream commit a1f4170dec ]

We don't need all the complex arithmetic for BCMs utilizing enable_mask,
as all we need to do is to determine whether there's any user (or
keepalive) asking for it to be on.

Separate the logic for such BCMs for a small speed boost.

694ddc5bf3 scsi: fcoe: Fix potential deadlock on &fip->ctlr_lock
[ Upstream commit 1a19755519 ]

There is a long call chain that &fip->ctlr_lock is acquired by isr
fnic_isr_msix_wq_copy() under hard IRQ context. Thus other process context
code acquiring the lock should disable IRQ, otherwise deadlock could happen
if the IRQ preempts the execution while the lock is held in process context
on the same CPU.

[ISR]
fnic_isr_msix_wq_copy()
 -> fnic_wq_copy_cmpl_handler()
 -> fnic_fcpio_cmpl_handler()
 -> fnic_fcpio_flogi_reg_cmpl_handler()
 -> fnic_flush_tx()
 -> fnic_send_frame()
 -> fcoe_ctlr_els_send()
 -> spin_lock_bh(&fip->ctlr_lock)

[Process Context]
1. fcoe_ctlr_timer_work()
 -> fcoe_ctlr_flogi_send()
 -> spin_lock_bh(&fip->ctlr_lock)

2. fcoe_ctlr_recv_work()
 -> fcoe_ctlr_recv_handler()
 -> fcoe_ctlr_recv_els()
 -> fcoe_ctlr_announce()
 -> spin_lock_bh(&fip->ctlr_lock)

3. fcoe_ctlr_recv_work()
 -> fcoe_ctlr_recv_handler()
 -> fcoe_ctlr_recv_els()
 -> fcoe_ctlr_flogi_retry()
 -> spin_lock_bh(&fip->ctlr_lock)

4. -> fcoe_xmit()
 -> fcoe_ctlr_els_send()
 -> spin_lock_bh(&fip->ctlr_lock)

spin_lock_bh() is not enough since fnic_isr_msix_wq_copy() is a
hardirq.

These flaws were found by an experimental static analysis tool I am
developing for irq-related deadlock.

The patch fix the potential deadlocks by spin_lock_irqsave() to disable
hard irq.

9406ad6d6c coresight: trbe: Fix TRBE potential sleep in atomic context
[ Upstream commit c0a232f1e1 ]

smp_call_function_single() will allocate an IPI interrupt vector to
the target processor and send a function call request to the interrupt
vector. After the target processor receives the IPI interrupt, it will
execute arm_trbe_remove_coresight_cpu() call request in the interrupt
handler.

According to the device_unregister() stack information, if other process
is useing the device, the down_write() may sleep, and trigger deadlocks
or unexpected errors.

Add a helper arm_trbe_disable_cpu() to disable TRBE precpu irq and reset
per TRBE.
Simply call arm_trbe_remove_coresight_cpu() directly without useing the
smp_call_function_single(), which is the same as registering the TRBE
coresight device.

1c5fb9c795 f2fs: fix to account gc stats correctly
[ Upstream commit 9bf1dcbdfd ]

As reported, status debugfs entry shows inconsistent GC stats as below:

GC calls: 6008 (BG: 6161)
  - data segments : 3053 (BG: 3053)
  - node segments : 2955 (BG: 2955)

Total GC calls is larger than BGGC calls, the reason is:
- f2fs_stat_info.call_count accounts total migrated section count
by f2fs_gc()
- f2fs_stat_info.bg_gc accounts total call times of f2fs_gc() from
background gc_thread

Another issue is gc_foreground_calls sysfs entry shows total GC call
count rather than FGGC call count.

This patch changes as below for fix:
- account GC calls and migrated segment count separately
- support to account migrated section count if it enables large section
mode
- fix to show correct value in gc_foreground_calls sysfs entry

Compression option in inode should not be changed after they have

Thread A				Thread B
- f2fs_ioc_set_compress_option
 - check f2fs_is_mmap_file()
 - check get_dirty_pages()
 - check F2FS_HAS_BLOCKS()
					- f2fs_file_mmap
					 - set_inode_flag(FI_MMAP_FILE)
					- fault
					 - do_page_mkwrite

					  - f2fs_get_block_locked
					 - fault_dirty_shared_page
					  - set_page_dirty
 - update i_compress_algorithm
 - update i_log_cluster_size
 - update i_cluster_size

Avoid such race condition by covering f2fs_file_mmap() w/ i_sem lock,
meanwhile add mmap file check condition in f2fs_may_compress() as well.

38b0ebc048 media: ov2680: Fix ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY not working
[ Upstream commit c0e97a4b4f ]

ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY was getting
the try_fmt v4l2_mbus_framefmt struct from the passed in sd_state
and then storing the contents of that into the return by reference
format->format struct.

While the right thing to do would be filling format->format based on
the just looked up mode and then store the results of that in
sd_state->pads[0].try_fmt .

Before the previous change introducing ov2680_fill_format() this
resulted in ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY always
returning the zero-ed out sd_state->pads[0].try_fmt in format->format
breaking callers using this.

After the introduction of ov2680_fill_format() which at least
initializes sd_state->pads[0].try_fmt properly, format->format
is now always being filled with the default 800x600 mode set by
ov2680_init_cfg() independent of the actual requested mode.

Move the filling of format->format with ov2680_fill_format() to
before the if (which == V4L2_SUBDEV_FORMAT_TRY) and then store
the filled in format->format in sd_state->pads[0].try_fmt to
fix this.

Note this removes the fmt local variable because IMHO having a local
variable which points to a sub-struct of one of the function arguments
just leads to confusion when reading the code.

Add a ov2680_fill_format() helper function and use this everywhere were

This is a preparation patch for fixing ov2680_set_fmt()
which == V4L2_SUBDEV_FORMAT_TRY calls not properly filling in
the passed in v4l2_mbus_framefmt struct.

Note that for ov2680_init_cfg() this now simply always fills
the try_fmt struct of the passed in sd_state. This is correct because
ov2680_init_cfg() is never called with a NULL sd_state so the old
sd_state check is not necessary.

ov2680_vflip_disable() / ov2680_hflip_disable() pass BIT(0) instead of
0 as value to ov2680_mod_reg().

While fixing this also:

1. Stop having separate enable/disable functions for hflip / vflip
2. Move the is_streaming check, which is unique to hflip / vflip
   into the ov2680_set_?flip() functions.

for a nice code cleanup.

f3ac838162 media: ov2680: Fix ov2680_bayer_order()
[ Upstream commit 50a7bad4e0 ]

The index into ov2680_hv_flip_bayer_order[] should be 0-3, but
ov2680_bayer_order() was using 0 + BIT(2) + (BIT(2) << 1) as
max index, while the intention was to use: 0 + 1 + 2 as max index.

Fix the index calculation in ov2680_bayer_order(), while at it
also just use the ctrl values rather then reading them back using
a slow i2c-read transaction.

This also allows making the function void, since there now are
no more i2c-reads to error check.

Note the check for the ctrls being NULL is there to allow
adding an ov2680_fill_format() helper later, which will call
ov2680_set_bayer_order() during probe() before the ctrls are created.

afccb9524a media: ov2680: Remove auto-gain and auto-exposure controls
[ Upstream commit 7b5a42e6ae ]

Quoting the OV2680 datasheet:

"3.2 exposure and gain control

In the OV2680, the exposure time and gain are set manually from an external
controller. The OV2680 supports manual gain and exposure control only for
normal applications, no auto mode."

And indeed testing with the atomisp_ov2680 fork of ov2680.c has shown that
auto-exposure and auto-gain do not work.

Note that the code setting the auto-exposure flag was broken, callers
of ov2680_exposure_set() were directly passing !!ctrls->auto_exp->val as
"bool auto_exp" value, but ctrls->auto_exp is a menu control with:

enum  v4l2_exposure_auto_type {
        V4L2_EXPOSURE_AUTO = 0,
        V4L2_EXPOSURE_MANUAL = 1,
	...

So instead of passing !!ctrls->auto_exp->val they should have been passing
ctrls->auto_exp->val == V4L2_EXPOSURE_AUTO, iow the passed value was
inverted of what it should have been.

Also remove ov2680_g_volatile_ctrl() since without auto support the gain
and exposure controls are not volatile.

This also fixes the control values not being properly applied in
ov2680_mode_set(). The 800x600 mode register-list also sets gain,
exposure and vflip overriding the last set ctrl values.

ov2680_mode_set() does call ov2680_gain_set() and ov2680_exposure_set()
but did this before writing the mode register-list, so these values
would still be overridden by the mode register-list.

Add a v4l2_ctrl_handler_setup() call after writing the mode register-list
to restore all ctrl values. Also remove the ctrls->gain->is_new check from
ov2680_gain_set() so that the gain always gets restored properly.

Last since ov2680_mode_set() now calls v4l2_ctrl_handler_setup(), remove
the v4l2_ctrl_handler_setup() call after ov2680_mode_restore() since
ov2680_mode_restore() calls ov2680_mode_set().

47b4081e35 media: ov5640: Fix initial RESETB state and annotate timings
[ Upstream commit a210df337c ]

The initial state of RESETB input signal of OV5640 should be
asserted, i.e. the sensor should be in reset. This is not the
case, make it so.

Since the subsequent assertion of RESETB signal is no longer
necessary and the timing of the power sequencing could be
slightly adjusted, add annotations to the delays which match
OV5640 datasheet rev. 2.03, both:
  figure 2-3 power up timing with internal DVDD
  figure 2-4 power up timing with external DVDD source

The 5..10ms delay between PWDN assertion and RESETB assertion
is not even documented in the power sequencing diagram, and
with this reset fix, it is no longer even necessary.

9990c80ec1 HID: input: Support devices sending Eraser without Invert
[ Upstream commit 276e14e6c3 ]

Some digitizers (notably XP-Pen Artist 24) do not report the Invert
usage when erasing.  This causes the device to be permanently stuck with
the BTN_TOOL_RUBBER tool after sending Eraser, as Invert is the only
usage that can release the tool.  In this state, Touch and Inrange are
no longer reported to userspace, rendering the pen unusable.

Prior to commit 87562fcd13 ("HID: input: remove the need for
HID_QUIRK_INVERT"), BTN_TOOL_RUBBER was never set and Eraser events were
simply translated into BTN_TOUCH without causing an inconsistent state.

Introduce HID_QUIRK_NOINVERT for such digitizers and detect them during
hidinput_configure_usage().  This quirk causes the tool to be released
as soon as Eraser is reported as not set.  Set BTN_TOOL_RUBBER in
input->keybit when mapping Eraser.

3bcc4c2a09 drivers: base: Free devm resources when unregistering a device
[ Upstream commit 699fb50d99 ]

In the current code, devres_release_all() only gets called if the device
has a bus and has been probed.

This leads to issues when using bus-less or driver-less devices where
the device might never get freed if a managed resource holds a reference
to the device. This is happening in the DRM framework for example.

We should thus call devres_release_all() in the device_del() function to
make sure that the device-managed actions are properly executed when the
device is unregistered, even if it has neither a bus nor a driver.

This is effectively the same change than commit 2f8d16a996 ("devres:
release resources on device_del()") that got reverted by commit
a525a3ddea ("driver core: free devres in device_release") over
memory leaks concerns.

This patch effectively combines the two commits mentioned above to
release the resources both on device_del() and device_release() and get
the best of both worlds.

[ Upstream commit 11e0a7c8e0 ]

Commit 567f97bd38 ("media: ipu3-cio2: support multiple sensors and VCMs

the name field of the software_node struct used for the vcm.

But the software_node struct is much longer lived then the current
stack-frame, so this is no good.

Instead extend the ipu_node_names struct with an extra field to store
the vcm software_node name and use that.

Note this also changes the length of the allocated buffer from
ACPI_ID_LEN + 4 to 16. the name is filled with "<ipu_vcm_types[x]>-%u"
where ipu_vcm_types[x] is not an ACPI_ID. The maximum length of
the strings in the ipu_vcm_types[] array is 11 + 5 bytes for "-255\0"
means 16 bytes are needed in the worst case scenario.

258e4784b8 media: cec: core: add adap_nb_transmit_canceled() callback
[ Upstream commit da53c36ddd ]

A potential deadlock was found by Zheng Zhang with a local syzkaller
instance.

The problem is that when a non-blocking CEC transmit is canceled by calling
cec_data_cancel, that in turn can call the high-level received() driver
callback, which can call cec_transmit_msg() to transmit a new message.

The cec_data_cancel() function is called with the adap->lock mutex held,
and cec_transmit_msg() tries to take that same lock.

The root cause is that the received() callback can either be used to pass
on a received message (and then adap->lock is not held), or to report a
canceled transmit (and then adap->lock is held).

This is confusing, so create a new low-level adap_nb_transmit_canceled
callback that reports back that a non-blocking transmit was canceled.

And the received() callback is only called when a message is received,
as was the case before commit f9d0ecbf56 ("media: cec: correctly pass
on reply results") complicated matters.

b3fdfdb5d8 iommu/qcom: Disable and reset context bank before programming
[ Upstream commit 9f3fef23d9 ]

Writing	the new	TTBRs, TCRs and MAIRs on a previously enabled
context bank may trigger a context fault, resulting in firmware
driven AP resets: change the domain initialization programming
sequence to disable the context bank(s) and to also clear the
related fault address (CB_FAR) and fault status (CB_FSR)
registers before writing new values to TTBR0/1, TCR/TCR2, MAIR0/1.

58c928d4ae fsi: aspeed: Reset master errors after CFAM reset
[ Upstream commit 52300909f4 ]

It has been observed that sometimes the FSI master will return all 0xffs
after a CFAM has been taken out of reset, without presenting any error.
Resetting the FSI master errors resolves the issue.

d95b6f3ba7 IB/uverbs: Fix an potential error pointer dereference
[ Upstream commit 26b7d1a271 ]

smatch reports the warning below:
drivers/infiniband/core/uverbs_std_types_counters.c:110
ib_uverbs_handler_UVERBS_METHOD_COUNTERS_READ() error: 'uattr'
dereferencing possible ERR_PTR()

The return value of uattr maybe ERR_PTR(-ENOENT), fix this by checking
the value of uattr before using it.

[ Upstream commit 9e03dbea2b ]

Currently, the affinity between QP cache and CQ cache is not
considered when assigning QPN, it will affect the message rate of HW.

Allocate QPN from QP cache with better CQ affinity to get better
performance.

bf6f879fde RDMA/hns: Fix incorrect post-send with direct wqe of wr-list
[ Upstream commit 706efac447 ]

Currently, direct wqe is not supported for wr-list. RoCE driver excludes
direct wqe for wr-list by judging whether the number of wr is 1.

For a wr-list where the second wr is a length-error atomic wr, the
post-send driver handles the first wr and adds 1 to the wr number counter
firstly. While handling the second wr, the driver finds out a length error
and terminates the wr handle process, remaining the counter at 1. This
causes the driver mistakenly judges there is only 1 wr and thus enters
the direct wqe process, carrying the current length-error atomic wqe.

This patch fixes the error by adding a judgement whether the current wr
is a bad wr. If so, use the normal doorbell process but not direct wqe
despite the wr number is 1.
