Memory for the "struct device" for any given device isn't supposed to
be released until the device's release() is called. This is important
because someone might be holding a kobject reference to the "struct
device" and might try to access one of its members even after any
other cleanup/uninitialization has happened.

Code analysis of ti-sn65dsi86 shows that this isn't quite right. When
the code was written, it was believed that we could rely on the fact
that the child devices would all be freed before the parent devices
and thus we didn't need to worry about a release() function. While I
still believe that the parent's "struct device" is guaranteed to
outlive the child's "struct device" (because the child holds a kobject
reference to the parent), the parent's "devm" allocated memory is a
different story. That appears to be freed much earlier.

Let's make this better for ti-sn65dsi86 by allocating each auxiliary
with kzalloc and then free that memory in the release().

Drivers that can delegate waits to the firmware/GPU pass the scheduled
fence to drm_sched_job_add_dependency(), and issue wait commands to
the firmware/GPU at job submission time. For this to be possible, they
need all their 'native' dependencies to have a valid parent since this
is where the actual HW fence information are encoded.

In drm_sched_main(), we currently call drm_sched_fence_set_parent()
after drm_sched_fence_scheduled(), leaving a short period of time
during which the job depending on this fence can be submitted.

Since setting parent and signaling the fence are two things that are
kinda related (you can't have a parent if the job hasn't been scheduled),
it probably makes sense to pass the parent fence to
drm_sched_fence_scheduled() and let it call drm_sched_fence_set_parent()
before it signals the scheduled fence.

Here is a detailed description of the race we are fixing here:

Thread A				Thread B

- calls drm_sched_fence_scheduled()
- signals s_fence->scheduled which
  wakes up thread B

					- entity dep signaled, checking
					  the next dep
					- no more deps waiting
					- entity is picked for job
					  submission by drm_gpu_scheduler
					- run_job() is called
					- run_job() tries to
					  collect native fence info from
					  s_fence->parent, but it's
					  NULL =>
					  BOOM, we can't do our native
					  wait

- calls drm_sched_fence_set_parent()

Commit 5d844091 ("drm/scdc-helper: Pimp SCDC debugs") changed the scdc
interface to pick up an i2c adapter from a connector instead. However, in
the case of dw-hdmi, the wrong connector was being used to pass i2c adapter
information, since dw-hdmi's embedded connector structure is only populated
when the bridge attachment callback explicitly asks for it.

drm-meson is handling connector creation, so this won't happen, leading to
a NULL pointer dereference.

Fix it by having scdc functions access dw-hdmi's current connector pointer
instead, which is assigned during the bridge enablement stage.

drm_sched_entity_kill_jobs_cb() logic is omitting the last fence popped
from the dependency array that was waited upon before
drm_sched_entity_kill() was called (drm_sched_entity::dependency field),
so we're basically waiting for all dependencies except one.

In theory, this wait shouldn't be needed because resources should have
their users registered to the dma_resv object, thus guaranteeing that
future jobs wanting to access these resources wait on all the previous
users (depending on the access type, of course). But we want to keep
these explicit waits in the kill entity path just in case.

Let's make sure we keep all dependencies in the array in
drm_sched_job_dependency(), so we can iterate over the array and wait
in drm_sched_entity_kill_jobs_cb().

We also make sure we wait on drm_sched_fence::finished if we were
originally asked to wait on drm_sched_fence::scheduled. In that case,
we assume the intent was to delegate the wait to the firmware/GPU or
rely on the pipelining done at the entity/scheduler level, but when
killing jobs, we really want to wait for completion not just scheduling.

v2:
- Don't evict deps in drm_sched_job_dependency()

v3:
- Always wait for drm_sched_fence::finished fences in
  drm_sched_entity_kill_jobs_cb() when we see a sched_fence

v4:
- Fix commit message
- Fix a use-after-free bug

v5:
- Flag deps on which we should only wait for the scheduled event
  at insertion time

v6:
- Back to v4 implementation
- Add Christian's R-b

When an ATA port is resumed from sleep, the port is reset and a power
management request issued to libata EH to reset the port and rescanning
the device(s) attached to the port. Device rescanning is done by
scheduling an ata_scsi_dev_rescan() work, which will execute
scsi_rescan_device().

However, scsi_rescan_device() takes the generic device lock, which is
also taken by dpm_resume() when the SCSI device is resumed as well. If
a device rescan execution starts before the completion of the SCSI
device resume, the rcu locking used to refresh the cached VPD pages of
the device, combined with the generic device locking from
scsi_rescan_device() and from dpm_resume() can cause a deadlock.

Avoid this situation by changing struct ata_port scsi_rescan_task to be
a delayed work instead of a simple work_struct. ata_scsi_dev_rescan() is
modified to check if the SCSI device associated with the ATA device that
must be rescanned is not suspended. If the SCSI device is still
suspended, ata_scsi_dev_rescan() returns early and reschedule itself for
execution after an arbitrary delay of 5ms.

ASoC: Fixes for v6.4

A couple more fixes for v6.4, one fixing a misleading error log and
another stopping us seeing spurious failures setting the master volume
on some Tegra systems introduced by a change to how we calculate delay
times.

This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for
HEM devices which supports native DSD. Prior to this change Linux kernel
was not enabling native DSD playback for HEM devices, and as a result,
DSD audio was being converted to PCM "on the fly". HEM devices,
when connected to the system, would only play audio in PCM format,
even if the source material was in DSD format. With the addition of new
VENDOR_FLG in the quircks.c file, the devices are now correctly
recognized, and raw DSD data is transmitted to the device,
allowing for native DSD playback.

As reported in the bugzilla below, the PM resume of a UAC3 device may
fail due to the incomplete power state change, stuck at D1.  The
reason is that the driver expects the full D0 power state change only
at hw_params, while the normal PCM resume procedure doesn't call
hw_params.

For fixing the bug, we add the same power state update to D0 at the
prepare callback, which is certainly called by the resume procedure.

Note that, with this change, the power state change in the hw_params
becomes almost redundant, since snd_usb_hw_params() doesn't touch the
parameters (at least it tires so).  But dropping it is still a bit
risky (e.g. we have the media-driver binding), so I leave the D0 power
state change in snd_usb_hw_params() as is for now.

Although snd_seq_oss_midi_open() and snd_seq_oss_midi_close() can be
called concurrently from different code paths, we have no proper data
protection against races.  Introduce open_mutex to each seq_oss_midi
object for avoiding the races.

Pull networking fixes from Jakub Kicinski:
 "Including fixes from wireless, and netfilter.

  Selftests excluded - we have 58 patches and diff of +442/-199, which
  isn't really small but perhaps with the exception of the WiFi locking
  change it's old(ish) bugs.

  We have no known problems with v6.4.

  The selftest changes are rather large as MPTCP folks try to apply
  Greg's guidance that selftest from torvalds/linux should be able to
  run against stable kernels.

  Last thing I should call out is the DCCP/UDP-lite deprecation notices.
  We are fairly sure those are dead, but if we're wrong reverting them
  back in won't be fun.

   (max_sectors_kb) rather than every 64M (discard_max_bytes).

 - Extend DM core LOCKFS fix, made during 6.4 merge, to also fix race
   between do_mount and dm's do_suspend (in addition to the earlier
   fix's do_mount race with dm's do_resume).

 - Fix DM thin metadata operations to first check if the thin-pool is in
   "fail_io" mode; otherwise UAF can occur.

 - Fix DM thinp's call to __blkdev_issue_discard to use GFP_NOIO rather
   than GFP_NOWAIT (__blkdev_issue_discard cannot handle NULL return
   from bio_alloc).

Pull rdma fixes from Jason Gunthorpe:
 "This is an unusually large bunch of bug fixes for the later rc cycle,
  rxe and mlx5 both dumped a lot of things at once. rxe continues to fix
  itself, and mlx5 is fixing a bunch of "queue counters" related bugs.

  There is one highly notable bug fix regarding the qkey. This small
  security check was missed in the original 2005 implementation and it
  allows some significant issues.

  Summary:

   - Two rtrs bug fixes for error unwind bugs

   - Several rxe bug fixes:
      * Incorrect Rx packet validation
      * Using memory without a refcount
      * Syzkaller found use before initialization
      * Regression fix for missing locking with the tasklet conversion
        from this merge window

   - Have bnxt report the correct link properties to userspace, this was
     a regression in v6.3

   - Several mlx5 bug fixes:
      * Kernel crash triggerable by userspace for the RAW ethernet
        profile
      * Defend against steering refcounting issues created by userspace
      * Incorrect change of QP port affinity parameters in some LAG
        configurations

   - Fix mlx5 Q counters:
      * Do not over allocate Q counters to allow userspace to use the
        full port capacity
      * Kernel crash triggered by eswitch due to mis-use of Q counters
      * Incorrect mlx5_device for Q counters in some LAG configurations

   - Properly implement the IBA spec restricting privileged qkeys to
     root

   - Always an error when reading from a disassociated device's event
     queue
