'am33xx_pm_rtc_setup()' allocates some resources that must be freed on the

only updated the remove function.

[ Upstream commit 7de8681be2 ]
As per the kernel doc for usb_ep_dequeue(), it states that "this
routine is asynchronous, that is, it may return before the completion
routine runs". And indeed since v5.0 the dwc3 gadget driver updated
its behavior to place dequeued requests on to a cancelled list to be
given back later after the endpoint is stopped.
The free_ep() was incorrectly assuming that a request was ready to
be freed after calling dequeue which results in a use-after-free
in dwc3 when it traverses its cancelled list. Fix this by moving
the usb_ep_free_request() call to the callback itself in case the
ep is disabled.

The macros to classify different AML exception codes are broken. For
instance,
ACPI_ENV_EXCEPTION(Status)
will always evaluate to zero due to
#define AE_CODE_ENVIRONMENTAL 0x0000
#define ACPI_ENV_EXCEPTION(Status) (Status & AE_CODE_ENVIRONMENTAL)
Similarly, ACPI_AML_EXCEPTION(Status) will evaluate to a non-zero
value for error codes of type AE_CODE_PROGRAMMER, AE_CODE_ACPI_TABLES,
as well as AE_CODE_AML, and not just AE_CODE_AML as the name suggests.
This commit fixes those checks.

When the BMC150 accelerometer/magnetometer was added to the device tree,

the sensors from working in some cases.

[ Upstream commit 948c657cc4 ]
In contrast to the H6 (and later) manuals, the A64 datasheet does not
specify any limitations in the maximum possible frequency for eMMC
controllers.
However experimentation has found that a 150 MHz limit similar to other
SoCs and also the MMC0 and MMC1 controllers on the A64 seems to exist
for the MMC2 controller.
Limit the frequency for the MMC2 controller to 150 MHz in the SoC .dtsi.
The Pinebook seems to be the an odd exception, since it apparently seems
to work with 200 MHz as well, so overwrite this in its board .dts file.
Tested on a Pine64-LTS: 200 MHz HS-200 fails, 150 MHz HS-200 works.

The H6 manual explicitly lists a frequency limit of 150 MHz for the bus
frequency of the MMC controllers. So far we had no explicit limits in the
DT, which limited eMMC to the spec defined frequencies, or whatever the
driver defines (both Linux and FreeBSD use 52 MHz here).
Put those maximum frequencies in the SoC .dtsi, to allow higher speed
modes (which still would need to be explicitly enabled, per board).
Tested with an eMMC using HS-200 on a Pine H64. Running at the spec'ed
200 MHz indeed fails with I/O errors, but 150 MHz seems to work stably.

[ Upstream commit 941432d007 ]
The SD card on the SoPine SoM module is somewhat concealed, so was
originally defined as "non-removable".
However there is a working card-detect pin (tested on two different
SoM versions), and in certain SoM base boards it might be actually
accessible at runtime.
Also the Pine64-LTS shares the SoPine base .dtsi, so inherited the
non-removable flag, even though the SD card slot is perfectly accessible
and usable there. (It turns out that just *my* board has a broken card
detect switch, so I originally thought CD wouldn't work on the LTS.)
Drop the "non-removable" flag to describe the SD card slot properly.

In recent Allwinner SoCs the first USB host controller (HCI0) shares
the first PHY with the MUSB controller. Probably to make this sharing
work, we were avoiding to declare this in the DT. This has two
shortcomings:
- U-Boot (which uses the same .dts) cannot use this port in host mode
without a PHY linked, so we were loosing one USB port there.
- It requires the MUSB driver to be enabled and loaded, although we
don't actually use it.
To avoid those issues, let's add this PHY link to the H6 .dtsi file.
After all PHY port 0 *is* connected to HCI0, so we should describe
it as this.
This makes it work in U-Boot, also improves compatiblity when no MUSB
driver is loaded (for instance in distribution installers).

Unlike most MSM8916 boards, samsung-a5u uses WCN3660B instead of

to describe that configuration using the qcom,wcn3680 compatible.
However, as of commit 8490987bdb ("wcn36xx: Hook and identify RF_IRIS_WCN3680"),
the wcn36xx driver will now use the qcom,wcn3680 compatible
to enable functionality specific to WCN3680. In particular,

However, if the HCI_UART_SENDING check in hci_uart_tx_wakeup is done after
the loop breaks, but before HCI_UART_SENDING is cleared in
hci_uart_write_work, the schedule_work is skipped incorrectly.
Fix this race by changing the order of HCI_UART_SENDING and
HCI_UART_TX_WAKEUP modification.

commit 700cb70730 upstream.
The PCM stop operation sets the stop_operating flag for indicating the
sync_stop post-process. This flag is, however, set unconditionally
even if the PCM trigger weren't issued. This may lead to
inconsistency in the driver side.
Correct the code to set stop_operating flag only after the trigger
STOP is actually called.

commit 2c87c1a49c upstream.
The current PCM code calls the sync_stop at the resume action due to
the analogy to the PCM prepare call pattern. But, it makes little
sense, as the sync should have been done rather at the suspend time,
not at the resume time.
This patch corrects the sync_stop call at suspend/resume to assure the
sync before finishing the suspend.

commit 29bb274e94 upstream.
The PCM core should perform the sync for the pending stop operations
at disconnection. Otherwise it may lead to unexpected access.
Currently the old user of sync_stop, USB-audio driver, has its own
sync, so this isn't needed, but it's better to guarantee the sync in
the PCM core level.
This patch adds the missing sync_stop call at PCM disconnection
callback. It also assures the IRQ sync if it's specified in the
card. snd_pcm_sync_stop() is slightly modified to be called also for
any PCM substream object now.

MIPS uses its own declaration of rwdata, and thus it should be kept

missing from the linker script, which emits the following ld

commit fb3c293b82 upstream.
The commit f274baa49b ("ALSA: usb-audio: Allow non-vmalloc buffer
for PCM buffers") introduced the mode to allocate coherent pages for
PCM buffers, and it used bus->controller device as its DMA device.
It turned out, however, that bus->sysdev is a more appropriate device
to be used for DMA mapping in HCD code.
This patch corrects the device reference accordingly.
Note that, on most platforms, both point to the very same device,
hence this patch doesn't change anything practically. But on
platforms like xhcd-plat hcd, the change becomes effective.

commit 41e76c8566 upstream.
bfq_setup_cooperator() uses bfqd->in_serv_last_pos so detect whether it
makes sense to merge current bfq queue with the in-service queue.
However if the in-service queue is freshly scheduled and didn't dispatch
any requests yet, bfqd->in_serv_last_pos is stale and contains value
from the previously scheduled bfq queue which can thus result in a bogus
decision that the two queues should be merged. This bug can be observed
for example with the following fio jobfile:
[global]
direct=0
ioengine=sync
invalidate=1
size=1g
rw=read
[reader]
numjobs=4
directory=/mnt
where the 4 processes will end up in the one shared bfq queue although
they do IO to physically very distant files (for some reason I was able to
observe this only with slice_idle=1ms setting).
Fix the problem by invalidating bfqd->in_serv_last_pos when switching
in-service queue.
