A failure in xe_force_wake_get() no longer increments the domain's
refcount. Therefore, if xe_force_wake_get() fails during forcewake
debugfs open, return an error. This ensures there are no valid file
descriptors to close via forcewake debugfs, preventing refcount
mismanagement.
v3
- return xe_wakeref_t instead of int in xe_force_wake_get()
v5
- return unsigned int from xe_force_wake_get()
v6
- Use helper xe_force_wake_ref_has_domain()
to determine the status of the call.

xe_force_wake_get() now returns the reference count-incremented domain
mask. If it fails for individual domains, the return value will always
be 0. However, for XE_FORCEWAKE_ALL, it may return a non-zero value even
in the event of failure. Update the return handling of xe_force_wake_get()
to reflect this behavior, and ensure that the return value is passed as
input to xe_force_wake_put().
v3
- return xe_wakeref_t instead of int in xe_force_wake_get()
- xe_force_wake_put() error doesn't need to be escalated/considered as
probing error. It internally WARNS on domain ack failure.

Instead of calling xe_force_wake_put on all domains that were input to
xe_force_wake_get, call _put only on the domains whose reference counts
were successfully incremented by the _get call. Since the return value
of _get can be a mask that does not match any specific value in the enum
xe_force_wake_domains, change the input parameter of _put to unsigned int.

If an acknowledgment timeout occurs for a forcewake domain awake
request, do not increment the reference count for the domain. This
ensures that subsequent _get calls do not incorrectly assume the domain
is awake. The return value is a mask of domains that got refcounted,
and these domains need to be provided for subsequent xe_force_wake_put
call.
While at it, add simple kernel-doc for xe_force_wake_get()
v3
- Use explicit type for mask (Michal/Badal)
- Improve kernel-doc (Michal)
- Use unsigned int instead of abusing enum (Michal)
v5
- Use unsigned int for return (MattB/Badal/Rodrigo)
- use xe_gt_WARN for domain awake ack failure (Badal/Rodrigo)

- Remove unnecessary information in kernel-doc (Michal)

When btrfs reserves an extent and does not use it (e.g, by an error), it
calls btrfs_free_reserved_extent() to free the reserved extent. In the
process, it calls btrfs_add_free_space() and then it accounts the region
bytes as block_group->zone_unusable.
However, it leaves the space_info->bytes_zone_unusable side not updated. As
a result, ENOSPC can happen while a space_info reservation succeeded. The
reservation is fine because the freed region is not added in
space_info->bytes_zone_unusable, leaving that space as "free". OTOH,
corresponding block group counts it as zone_unusable and its allocation
pointer is not rewound, we cannot allocate an extent from that block group.
That will also negate space_info's async/sync reclaim process, and cause an
ENOSPC error from the extent allocation process.
Fix that by returning the space to space_info->bytes_zone_unusable.
Ideally, since a bio is not submitted for this reserved region, we should
return the space to free space and rewind the allocation pointer. But, it
needs rework on extent allocation handling, so let it work in this way for
now.

When adding a explicit beautifier for the 'write' syscall when the BPF
based buffer collector was introduced there was a cut'n'paste error that
carried the syscall_fmt->errpid setting from a nearby syscall (waitid)
that returns a pid.
So the write return was being suppressed by the return pretty printer,
remove that field, reverting it back to the default return handler, that
prints positive numbers as-is and interpret negative values as errnos.
I actually introduced the problem while making Howard's original patch
work just with the 'write' syscall, as we couldn't just look for any
buffers, the ones that are filled in by the kernel couldn't use the same
sys_enter BPF collector.

afs_wake_up_async_call() can incur lock recursion. The problem is that it
is called from AF_RXRPC whilst holding the ->notify_lock, but it tries to
take a ref on the afs_call struct in order to pass it to a work queue - but
if the afs_call is already queued, we then have an extraneous ref that must
be put... calling afs_put_call() may call back down into AF_RXRPC through
rxrpc_kernel_shutdown_call(), however, which might try taking the
->notify_lock again.
This case isn't very common, however, so defer it to a workqueue. The oops
looks something like:

In the I/O locking code borrowed from NFS into netfslib, i_rwsem is held
locked across a buffered write - but this causes a performance regression
in cifs as it excludes buffered reads for the duration (cifs didn't use any
locking for buffered reads).
Mitigate this somewhat by downgrading the i_rwsem to a read lock across the
buffered write. This at least allows parallel reads to occur whilst
excluding other writes, DIO, truncate and setattr.
Note that this shouldn't be a problem for a buffered write as a read
through an mmap can circumvent i_rwsem anyway.
Also note that we might want to make this change in NFS also.

Commit 44aff8e31080 ("phy: qcom-qmp-combo: clean up probe
initialisation") removed most users of the platform device driver data,
but mistakenly also removed the initialisation despite the data still
being used in the runtime PM callbacks.
The initialisation was soon after restored by commit 83a0bbe39b17 ("phy:
qcom-qmp-combo: add support for updated sc8280xp binding") but now
happens slightly later during probe. This should not cause any trouble
currently as runtime PM needs to be enabled manually through sysfs and
the platform device would not be suspended before the PHY has been
registered anyway.
Move the driver data initialisation to avoid a NULL-pointer dereference
on runtime suspend if runtime PM is ever enabled by default in this
driver.

The function parse_lfp_panel_dtd() is called when the driver
attempts to initialize the eDP connector, and it allocates memory,
which is recorded in panel->vbt.lfp_vbt_mode. However, since no
eDP panel is connected, the driver fails at intel_edp_init_dpcd()
and follows the failure path. Unfortunately, the allocated memory
is not freed in this case.
To fix this issue, free the memory in the failure path.

This is required to reset the DMA read/write pointers when the stream is
prepared and restarted after a call to snd_pcm_drain()/snd_pcm_drop().
Also, now that the stream is reset during stop, do not save LLP registers
in the case of STOP/suspend to avoid erroneous delay reporting.

In the case of a prepare callback after an xrun or when the PCM is
restarted after a call to snd_pcm_drain/snd_pcm_drop, avoid
reprogramming the SHIM registers but send the PDI stream number so that
the link DMA data can be set. This is needed for the case that the DMA
data is cleared when the PCM is stopped and restarted without being
closed.

When a PCM is restarted after a snd_pcm_drain/snd_pcm_drop(), the prepare
callback will be invoked and the hw_params will be set again. For the
HDA DAI's, the hw_params function handles this case already but not for
the non-HDA DAI's. So, add the check for link_prepared to verify if the
hw_params should be done again or not. Additionally, for SDW DAI's reset
the PCMSyCM registers as would be done in the case of a start after a
hw_free.

For aggregated DAIs, the node ID is set to the group_id during the DAI
widget's ipc_prepare op. With the current logic, setting the dai_index
for node_id in the dai_config is redundant as it will be overwritten
with the group_id anyway. Removing it will also prevent any accidental
clearing/resetting of the group_id for aggregated DAIs due to the
dai_config calls could that happen before the allocated group_id is
freed.
