ca0132 codec driver loads the firmware selectively depending on the
model in addition to the fallback of the default firmware. The code
works good, but a minor problem is that the current code seems
confusing for Clang where it spews a warning about uninitialized
variable.
This patch simplifies the code flow for such a false-positive
warning. After this refactoring, the ca0132_spec.alt_firmware_present
field is no longer used, hence it's eliminated as well.

Commit 2f31a67f01a8 ("usb: xhci: Prevent bus suspend if a port connect
change or polling state is detected") was intended to prevent ports that
were still link training from being forced to U3 suspend state mid
enumeration.
This solved enumeration issues for devices with slow link training.
Turns out some devices are stuck in the link training/polling state,
and thus that patch will prevent suspend completely for these devices.
This is seen with USB3 card readers in some MacBooks.
Instead of preventing suspend, give some time to complete the link
training. On successful training the port will end up as connected
and enabled.
If port instead is stuck in link training the bus suspend will continue
suspending after 360ms (10 * 36ms) timeout (tPollingLFPSTimeout).
Original patch was sent to stable, this one should go there as well

A suspended SS port in U3 link state will go to U0 when resumed, but
can almost immediately after that enter U1 or U2 link power save
states before host controller driver reads the port status.
Host controller driver only checks for U0 state, and might miss
the finished resume, leaving flags unclear and skip notifying usb
code of the wake.
Add U1 and U2 to the possible link states when checking for finished
port resume.

The PCM OSS emulation converts and transfers the data on the fly via
"plugins". The data is converted over the dynamically allocated
buffer for each plugin, and recently syzkaller caught OOB in this
flow.
Although the bisection by syzbot pointed out to the commit
65766ee0bf7f ("ALSA: oss: Use kvzalloc() for local buffer
allocations"), this is merely a commit to replace vmalloc() with
kvmalloc(), hence it can't be the cause. The further debug action
revealed that this happens in the case where a slave PCM doesn't
support only the stereo channels while the OSS stream is set up for a
mono channel. Below is a brief explanation:
At each OSS parameter change, the driver sets up the PCM hw_params
again in snd_pcm_oss_change_params_lock(). This is also the place
where plugins are created and local buffers are allocated. The
problem is that the plugins are created before the final hw_params is
determined. Namely, two snd_pcm_hw_param_near() calls for setting the
period size and periods may influence on the final result of channels,
rates, etc, too, while the current code has already created plugins
beforehand with the premature values. So, the plugin believes that
channels=1, while the actual I/O is with channels=2, which makes the
driver reading/writing over the allocated buffer size.
The fix is simply to move the plugin allocation code after the final
hw_params call.

The futex code requires that the user space addresses of futexes are 32bit
aligned. sys_futex() checks this in futex_get_keys() but the robust list
code has no alignment check in place.
As a consequence the kernel crashes on architectures with strict alignment
requirements in handle_futex_death() when trying to cmpxchg() on an
unaligned futex address which was retrieved from the robust list.

Commit 7640ead93924 ("bpf: verifier: make sure callees don't prune
with caller differences") connected up parentage chains of all
frames of the stack. It didn't, however, ensure propagate_liveness()
propagates all liveness information along those chains.
This means pruning happening in the callee may generate explored
states with incomplete liveness for the chains in lower frames
of the stack.
The included selftest is similar to the prior one from commit
7640ead93924 ("bpf: verifier: make sure callees don't prune with
caller differences"), where callee would prune regardless of the
difference in r8 state.
Now we also initialize r9 to 0 or 1 based on a result from get_random().
r9 is never read so the walk with r9 = 0 gets pruned (correctly) after
the walk with r9 = 1 completes.
The selftest is so arranged that the pruning will happen in the
callee. Since callee does not propagate read marks of r8, the
explored state at the pruning point prior to the callee will
now ignore r8.
Propagate liveness on all frames of the stack when pruning.

Empty chunk do not have a bo associated with them so no need to pin/unpin
on suspend/resume.
This fix suspend/resume on 5.1rc1 when NOUVEAU_SVM is enabled.

When there is only one byte in a frag, the current calculation
using "(size + HNS3_MAX_BD_SIZE - 1) >> HNS3_MAX_BD_SIZE_OFFSET"
will return zero, because HNS3_MAX_BD_SIZE is 65535 and
HNS3_MAX_BD_SIZE_OFFSET is 16. So it will cause tx error when
a frag's size is one byte.
This patch fixes it by using DIV_ROUND_UP.

As it stands if a shrink is delayed because of an outstanding
rehash, we will go into a rescheduling loop without ever doing
the rehash.
This patch fixes this by still carrying out the rehash and then
rescheduling so that we can shrink after the completion of the
rehash should it still be necessary.
The return value of EEXIST captures this case and other cases
(e.g., another thread expanded/rehashed the table at the same
time) where we should still proceed with the rehash.
Fixes: da20420f83ea ("rhashtable: Add nested tables")

When registering struct net_device, it will call
register_netdevice ->
netdev_register_kobject ->
device_initialize(dev);
dev_set_name(dev, "%s", ndev->name)
device_add(dev)
register_queue_kobjects(ndev)
In netdev_register_kobject(), if device_add(dev) or
register_queue_kobjects(ndev) failed. Register_netdevice()
will return error, causing netdev_freemem(ndev) to be
called to free net_device, however put_device(&dev->dev)->..->
kobject_cleanup() won't be called, resulting in a memory leak.
