commit 5d1b71226d upstream.
The altsetting sanity check in set_sync_ep_implicit_fb_quirk() was
checking for there to be at least one altsetting but then went on to
access the second one, which may not exist.
This could lead to random slab data being used to initialise the sync
endpoint in snd_usb_add_endpoint().

snd_seq_info_timer_read() reads the information of the timer assigned

This patch applies the missing q->timer_mutex lock while accessing the
timer object as well as a slight code change to adapt the standard

commit a14bf98c04 upstream.
In current driver, locks can be taken as follows:
- Register access: take a lock on regmap config and then on clock.
- Master clock provider: take a lock on clock and then on regmap config.
This can lead to the circular locking summarized below.
Remove peripheral clock management through regmap framework, and manage
peripheral clock in driver instead. On register access, lock on clock
is taken first, which allows to avoid possible locking issue.

commit 85578bbd64 upstream.
For some reason, attempting to route audio through QDSP6 on MSM8916
causes the RX interpolation path to get "stuck" after playing audio
a few times. In this situation, the analog codec part is still working,
but the RX path in the digital codec stops working, so you only hear
the analog parts powering up. After a reboot everything works again.
So far I was not able to reproduce the problem when using lpass-cpu.
The downstream kernel driver avoids this by resetting the RX
interpolation path after use. In mainline we do something similar
for the TX decimator (LPASS_CDC_CLK_TX_RESET_B1_CTL), but the
interpolator reset (LPASS_CDC_CLK_RX_RESET_CTL) got lost when the
msm8916-wcd driver was split into analog and digital.
Fix this problem by adding the reset to
msm8916_wcd_digital_enable_interpolator().

Commit d878970f6c ("bus: ti-sysc: Add separate functions for handling

introduced an issue where we do not necessarily allocate a slot for both
fck and ick clocks, but still assume fixed slots for enumerating over the
clocks.
Let's fix the issue by ensuring we always have slots for both fck and ick
even if we don't use ick, and don't attempt to enumerate optional clocks
if not allocated.
In the long run we might want to simplify things a bit by only allocating
space only for the optional clocks as we have only few devices with
optional clocks.

As the name of these GDSCs suggests, they are "votable" and in downstream
DT, they all have the property "qcom,no-status-check-on-disable", which
means that we should not poll the status bit when we disable them.
Luckily the VOTABLE flag already exists and it does exactly what we need,
so let's make use of it to make the warnings disappear.

commit 46c9585ed4 upstream.
The PMU registers are at least 0x18 bytes wide. Meson8b already uses a
size of 0x18. The structure of the PMU registers on Meson8 and Meson8b
is similar but not identical.
Meson8 and Meson8b have the following registers in common (starting at
AOBUS + 0xe0):
#define AO_RTI_PWR_A9_CNTL0 0xe0 (0x38 << 2)
#define AO_RTI_PWR_A9_CNTL1 0xe4 (0x39 << 2)
#define AO_RTI_GEN_PWR_SLEEP0 0xe8 (0x3a << 2)
#define AO_RTI_GEN_PWR_ISO0 0x4c (0x3b << 2)
Meson8b additionally has these three registers:
#define AO_RTI_GEN_PWR_ACK0 0xf0 (0x3c << 2)
#define AO_RTI_PWR_A9_MEM_PD0 0xf4 (0x3d << 2)
#define AO_RTI_PWR_A9_MEM_PD1 0xf8 (0x3e << 2)
Thus we can assume that the register size of the PMU IP blocks is
identical on both SoCs (and Meson8 just contains some reserved registers
in that area) because the CEC registers start right after the PMU
(AO_RTI_*) registers at AOBUS + 0x100 (0x40 << 2).
The upcoming power domain driver will need to read and write the
AO_RTI_GEN_PWR_SLEEP0 and AO_RTI_GEN_PWR_ISO0 registers, so the updated
size is needed for that driver to work.

[ Upstream commit 397eac17f8 ]
If journal is dirty when mount, it will be replayed but jbd2 sb log tail
cannot be updated to mark a new start because journal->j_flag has
already been set with JBD2_ABORT first in journal_init_common.
When a new transaction is committed, it will be recored in block 1
first(journal->j_tail is set to 1 in journal_reset). If emergency
restart happens again before journal super block is updated
unfortunately, the new recorded trans will not be replayed in the next
mount.
The following steps describe this procedure in detail.
1. mount and touch some files
2. these transactions are committed to journal area but not checkpointed
3. emergency restart
4. mount again and its journals are replayed
5. journal super block's first s_start is 1, but its s_seq is not updated
6. touch a new file and its trans is committed but not checkpointed
7. emergency restart again
8. mount and journal is dirty, but trans committed in 6 will not be
replayed.
This exception happens easily when this lun is used by only one node.
If it is used by multi-nodes, other node will replay its journal and its
journal super block will be updated after recovery like what this patch
does.

[ Upstream commit 2f42e05b94 ]
In some cases we seem to submit two transactions in a row, which
causes us to lose track of the first. If we then cancel the
request, we may still get an interrupt, which traverses a null
ds_run value.
So try to avoid starting a new transaction if the ds_run value
is set.
While this patch avoids the null pointer crash, I've had some
reports of the k3dma driver still getting confused, which
suggests the ds_run/ds_done value handling still isn't quite
right. However, I've not run into an issue recently with it
so I think this patch is worth pushing upstream to avoid the
crash.

[ Upstream commit 13b7955a02 ]
Standard kernel mutexes cannot be used in any way from interrupt or softirq
context, so the user_mutex which manages access to a call cannot be a mutex
since on a new call the mutex must start off locked and be unlocked within
the softirq handler to prevent userspace interfering with a call we're
setting up.
Commit a0855d24fc ("locking/mutex: Complain
upon mutex API misuse in IRQ contexts") causes big warnings to be splashed
in dmesg for each a new call that comes in from the server. Whilst it
*seems* like it should be okay, since the accept path uses trylock, there
are issues with PI boosting and marking the wrong task as the owner.
Fix this by not taking the mutex in the softirq path at all. It's not
obvious that there should be any need for it as the state is set before the
first notification is generated for the new call.
There's also no particular reason why the link-assessing ping should be
triggered inside the mutex. It's not actually transmitted there anyway,
but rather it has to be deferred to a workqueue.
Further, I don't think that there's any particular reason that the socket
notification needs to be done from within rx->incoming_lock, so the amount
of time that lock is held can be shortened too and the ping prepared before
the new call notification is sent.

is not honored anymore by the kernel in the case of gettimeofday().

[ Upstream commit e4dc9a4c31 ]
The sector size of the block layer is 512 bytes, but integrity interval
size might be different (in case of 4K block size of the media). At the
initiator side the virtual start sector is the one that was originally
submitted by the block layer (512 bytes) for the Reftag usage. The
initiator converts the Reftag to integrity interval units and sends it to
the target. So the target virtual start sector should be calculated at
integrity interval units. prepare_fn() and complete_fn() don't remap
correctly the Reftag when using incorrect units of the virtual start
sector, which leads to the following protection error at the device:
"blk_update_request: protection error, dev sdb, sector 2048 op 0x0:(READ)
flags 0x10000 phys_seg 1 prio class 0"
To fix that, set the seed in integrity interval units.
