commit 6d48b7912c upstream.
Clang doesn't like format strings that truncate a 32-bit
value to something shorter:
kernel/locking/lockdep.c:709:4: error: format specifies type 'short' but the argument has type 'int' [-Werror,-Wformat]
In this case, the warning is a slightly questionable, as it could realize
that both class->wait_type_outer and class->wait_type_inner are in fact
8-bit struct members, even though the result of the ?: operator becomes an
'int'.
However, there is really no point in printing the number as a 16-bit
'short' rather than either an 8-bit or 32-bit number, so just change
it to a normal %d.

When feature VIRTIO_NET_F_MTU is negotiated on mlx5_vdpa,
22 extra bytes worth of MTU length is shown in guest.
This is because the mlx5_query_port_max_mtu API returns
the "hardware" MTU value, which does not just contain the
Ethernet payload, but includes extra lengths starting
from the Ethernet header up to the FCS altogether.
Fix the MTU so packets won't get dropped silently.

Since commit 14d3d54052 ("perf session: Try to read pipe data from

pipes.
The commit exposed perf to the possiblity that the input is not a pipe
but the 'repipe' parameter gets used. That causes the printing because
perf inject sets 'repipe' to true always.
The 'repipe' parameter of perf_session__new() is used by 2 functions:
- perf_file_header__read_pipe()
- trace_report()
In both cases, the functions copy data to STDOUT_FILENO when 'repipe' is
true.
Fix by setting 'repipe' to true only if the output is a pipe.

[ Upstream commit 5620b135ae ]
We should set the platform device's driver data to NULL here so that
code doesn't assume the struct drm_device pointer is valid when it could
have been destroyed. The lifetime of this pointer is managed by a kref
but when msm_drm_init() fails we call drm_dev_put() on the pointer which
will free the pointer's memory. This driver uses the component model, so
there's sort of two "probes" in this file, one for the platform device
i.e. msm_pdev_probe() and one for the component i.e. msm_drm_bind(). The
msm_drm_bind() code is using the platform device's driver data to store
struct drm_device so the two functions are intertwined.
This relationship becomes a problem for msm_pdev_shutdown() when it
tests the NULL-ness of the pointer to see if it should call
drm_atomic_helper_shutdown(). The NULL test is a proxy check for if the
pointer has been freed by kref_put(). If the drm_device has been
destroyed, then we shouldn't call the shutdown helper, and we know that
is the case if msm_drm_init() failed, therefore set the driver data to
NULL so that this pointer liveness is tracked properly.

[ Upstream commit d24f847e54 ]
ct_label 0 is a default label each flow has and therefore
there can be rules that match on ct_label=0 without a prior
rule that set the ct_label to this value.
The ct_label value is not used directly in the HW rules and
instead it is mapped to some id within a defined range and this
id is used to set and match the metadata register which carries
the ct_label.
If we have a rule that matches on ct_label=0, the hw rule will
perform matching on a value that is != 0 because of the mapping
from label to id. Since the metadata register default value is
0 and it was never set before to anything else by an action that
sets the ct_label, there will always be a mismatch between that
register and the value in the rule.
To support such rule, a forced mapping of ct_label 0 to id=0
is done so that it will match the metadata register default
value of 0.

card->owner is a required property and since commit 81033c6b58 ("ALSA:

[ Upstream commit 2ea538dbee ]
A merge hint message needs some time to process before the merged
flow actually reaches the firmware, during which we may get duplicate
merge hints if there're more than one packet that hit the pre-merged
flow. And processing duplicate merge hints will cost extra host_ctx's
which are a limited resource.
Avoid the duplicate merge by using hash table to store the sub_flows
to be merged.

[ Upstream commit 03cb4d05b4 ]
Calling ncsi_stop_channel_monitor from channel_monitor is a guaranteed
deadlock on SMP because stop calls del_timer_sync on the timer that
invoked channel_monitor as its timer function.
Recognise the inherent race of marking the monitor disabled before
deleting the timer by just returning if enable was cleared. After
a timeout (the default case -- reset to START when response received)
just mark the monitor.enabled false.
If the channel has an entry on the channel_queue list, or if the
state is not ACTIVE or INACTIVE, then warn and mark the timer stopped
and don't restart, as the locking is broken somehow.

[ Upstream commit 6bf24dc0cc ]
In the if(skb_peek(arrvq) == skb) branch, it calls __skb_dequeue(arrvq) to get
the skb by skb = skb_peek(arrvq). Then __skb_dequeue() unlinks the skb from arrvq
and returns the skb which equals to skb_peek(arrvq). After __skb_dequeue(arrvq)
finished, the skb is freed by kfree_skb(__skb_dequeue(arrvq)) in the first time.
Unfortunately, the same skb is freed in the second time by kfree_skb(skb) after
the branch completed.
My patch removes kfree_skb() in the if(skb_peek(arrvq) == skb) branch, because
this skb will be freed by kfree_skb(skb) finally.
