Two versions of the original patch were sent but V1 was merged instead
of V2 due to a mistake.
So update to V2.
The advantage of V2 is that it completely avoids dereferencing the pointer,
even just to take the address, which may fix problems with some compilers.
Both versions work on my gcc 9.4 but use the safer one.

autofs_wait_queue structs should be freed if their wait_ctr becomes zero.
Otherwise they will be lost.
In this case an AUTOFS_IOC_EXPIRE_MULTI ioctl is done, then a new
waitqueue struct is allocated in autofs_wait(), its initial wait_ctr
equals 2. After that wait_event_killable() is interrupted (it returns
-ERESTARTSYS), so that 'wq->name.name == NULL' condition may be not
satisfied. Actually, this condition can be satisfied when
autofs_wait_release() or autofs_catatonic_mode() is called and, what is
also important, wait_ctr is decremented in those places. Upon the exit of
autofs_wait(), wait_ctr is decremented to 1. Then the unmounting process
begins: kill_sb calls autofs_catatonic_mode(), which should have freed the
waitqueues, but it only decrements its usage counter to zero which is not
a correct behaviour.
edit:imk
This description is of course not correct. The umount performed as a result
of an expire is a umount of a mount that has been automounted, it's not the
autofs mount itself. They happen independently, usually after everything
mounted within the autofs file system has been expired away. If everything
hasn't been expired away the automount daemon can still exit leaving mounts
in place. But expires done in both cases will result in a notification that
calls autofs_wait_release() with a result status. The problem case is the
summary execution of of the automount daemon. In this case any waiting
processes won't be woken up until either they are terminated or the mount
is umounted.
end edit: imk
So in catatonic mode we should free waitqueues which counter becomes zero.
edit: imk
Initially I was concerned that the calling of autofs_wait_release() and
autofs_catatonic_mode() was not mutually exclusive but that can't be the
case (obviously) because the queue entry (or entries) is removed from the
list when either of these two functions are called. Consequently the wait
entry will be freed by only one of these functions or by the woken process
in autofs_wait() depending on the order of the calls.

ASoC: Fix for v6.5
Not really a fix, but rather a licensing update for the fsl_micfil
driver.
SCMI v3.2 adds PERF protocol support to optionally define performance
domains that cannot be represented on a linear scale; the platform firmware
can declare the performance levels of a domain as being 'level indexed' and
provide an indicative frequency associated to each of those levels, with
such indexes not required anymore to be contiguous nor to satisfy any
linear-scaling constraint: when level-indexing is available for a domain,
the platform will expect to deal with SCMI requests using indexes instead
of performance levels for that domain.
Add level-indexing mode support to the PERF protocol implementation while
maintaining unchanged the protocol operations interface exposed by PERF;
all the required mapping from performamce levels/frequencies to the
corresponding level indexes is carried out transparently by the core PERF
protocol support: as a consequence no change is either required in any
SCMI driver using the PERF protocol, even when using level indexing.

Fix af_alg_alloc_areq() to initialise areq->first_rsgl.sgl.sgt.sgl to point

Without this, the gcm-aes-s390 driver will oops when it tries to do
gcm_walk_start() on req->dst because req->dst is set to the value of
areq->first_rsgl.sgl.sgl by _aead_recvmsg() calling
aead_request_set_crypt().
The problem comes if an empty ciphertext is passed: the loop in
af_alg_get_rsgl() just passes straight out and doesn't set areq->first_rsgl
up.
This isn't a problem on x86_64 using gcmaes_crypt_by_sg() because, as far

is enabled. Change it back to use AT803X_INTR_ENABLE_WOL for determining
the WoL status which is applicable on all chips supporting wol. Also update
the at803x_set_wol() function to only update the 1588 register on chips
having it. After this change, disabling wol at probe from commit
d7cd5e06c9 ("net: phy: at803x: disable WOL at probe") is no longer
needed. Change it to just disable the WoL bit in 1588 register for
AR8031/AR8033 to be aligned with AT803X_INTR_ENABLE_WOL in probe.
Fixes: 7beecaf7d5 ("net: phy: at803x: improve the WOL feature")

Add support for suspend and resume operation for PM in CAAM driver.
When the CAAM goes in suspend, the hardware is considered to do nothing.
On some platforms, the power of the CAAM is not turned off so it keeps
its configuration.
On other platforms, it doesn't so it is necessary to save the state of
the CAAM:
- JRs MID
- Address of input and output rings

The structure partid is not suitable to represent the DECO MID register.
This patch replace partid by masterid which is more appropriate.

The ELD (EDID-Like Data) is not updated when the HDMI cable
is plugged into different HDMI monitors.
This is because the EDID is not updated in the HDMI HPD function.
As a result, the ELD data remains unchanged and may not reflect
the capabilities of the newly connected HDMI sink device.
To address this issue, the handle_plugged_change function should move to
the bridge_atomic_enable and bridge_atomic_disable functions.
Make sure the EDID is properly updated before updating ELD.

This reverts commit 8ddce13ae6 ("drm/bridge: lt9611: Do not generate
HFP/HBP/HSA and EOT packet") to fix display regression on the Dragonboard
845c (SDM845) devboard.
There's a mismatch on the real action of the following flags:
- MIPI_DSI_MODE_VIDEO_NO_HSA
- MIPI_DSI_MODE_VIDEO_NO_HFP
- MIPI_DSI_MODE_VIDEO_NO_HBP
which leads to a non-working display on qcom platforms.

I have seen tcp_hashinfo starting at a non optimal location,
forcing input handlers to pull two cache lines instead of one,
and sharing a cache line that was dirtied more than necessary:
ffffffff83680600 b tcp_orphan_timer
ffffffff83680628 b tcp_orphan_cache
ffffffff8368062c b tcp_enable_tx_delay.__tcp_tx_delay_enabled
ffffffff83680630 B tcp_hashinfo
ffffffff83680680 b tcp_cong_list_lock
After this patch, ehash, ehash_locks, ehash_mask and ehash_locks_mask
are located in a read-only cache line.

At present hwc timeout value is a fixed value. This patch sets the hwc
timeout from the hardware. It now uses a new hardware capability
GDMA_DRV_CAP_FLAG_1_HWC_TIMEOUT_RECONFIG to query and set the value
in hwc_timeout.
