Same as we handle it in the regular wait for CS, we need to handle the

In device fini there was missing a call to release all pending user
interrupts. That can cause a process to be stuck inside the driver's
IOCTL of wait for interrupts, in case the device is removed or
simulator is killed at the same time.

In addition, also call to remove inactive codec job was missing.

Moreover, to prevent such errors in the future (where code is added
to reset path but not to device fini), we moved some common parts
to two dedicated functions:
cleanup_resources
take_release_locks

In case user interrupt arrived but the completion value is less than
the target value, we want to retry the wait.

However, before the retry we must reinitialize the completion object,
under spin-lock, so the wait function won't exit immediately because
the completion object is already completed (from the previous
interrupt).

Intel stress tests reported issues with the clock stop mode,
specifically when trying to do a system suspend while the link is
already pm_runtime suspended.

In this case, we need to disable the shim wake, but when the PCI
parent device is also pm_runtime suspended the SHIM registers are not
accessible.

Since this is an invalid corner case, this patch suggests a pm_runtime
resume of the entire bus to full power (parent+child devices) before
the system suspend so that the shim wake can be disabled.

Unlike the suspend operation, the .prepare callbacks are propagated
from root device to leaf devices. By adding a .prepare callback at the
SoundWire link level, we can double-check the pm_runtime status of the
device as well as its parent PCI device. When the problematic
configuration is detected, the device is pm_runtime resumed - which by
construction also resume its parent.

An additional loop is added to resume all child devices. In theory we
only need to restart the link, but doing so will also cause the
physical devices to synchronize and re-initialize, while their Linux
devices remain pm_runtime suspended. It's simpler to make sure the
codec devices are fully resumed so that we don't have to deal with
zombie states.

This additional loop could have been avoided by adding a .prepare
callback in SoundWire codec drivers. Functionally this would have been
equivalent. The rationale for implementing a loop at the link level is
only to reduce the amount of code required to deal at the codec level
with an Intel corner case - in other words keep codec drivers
independent from Intel platform-specific programming sequences.

The SoundWire Linux devices are created purely based on information
provided by platform firmware (e.g. ACPI DSDT table). When the kernel
finds a matching driver for the device address (_ADR), the probe will
initialize required data structures and initialize pm ops.

When the SoundWire link is started at a later point, the physical
devices will synchronize on the SoundWire frames and report their
attachment status, thereby triggering the enumeration and
initialization of device registers.

This two-step solution was a conscious design decision to allow e.g. a
driver to use sideband mechanisms to turn power rails on. This can
also allow OEMs to describe multiple platforms with the same DSDT
table, the devices that are not physically present in hardware.

The drawback of this approach is a bit of confusion, with more devices
than are actually present in hardware. This results in 'ghost'
devices, for which the driver successfully probes, but that will not
generate any traffic on the bus. suspend-resume transitions are
handled by drivers, and skipped when the devices are not physically
present.

This patch provides a work-around for a second-level of confusion in
platform firmware: some platforms only use HDaudio links, but
nevertheless expose SoundWire 'ghost' devices. This results in error
messages in the Intel driver while trying to suspend/resume these
links. The simplest solution is to add a boolean status flag to skip
all suspend/resume/wake sequences if the link was never started.

The power down sequence sets the link_up flag as false outside of the
mutex_lock. This is potentially unsafe.

In additional the flow in that sequence can be improved by first
testing if the link was powered, setting the link_up flag as false and
proceeding with the power down. In case the CPA bits cannot be
cleared, we only flag an error since we cannot deal with interrupts
any longer.

Pull drm fixes from Dave Airlie:
 "Regularly scheduled fixes. The ttm one solves a problem of GPU drivers
  failing to load if debugfs is off in Kconfig, otherwise the i915 and
  mediatek, and amdgpu fixes all fairly normal.

  Nouveau has a couple of display fixes, but it has a fix for a
  longstanding race condition in it's memory manager code, and the fix
  mostly removes some code that wasn't working properly and has no
  userspace users. This fix makes the diffstat kinda larger but in a
  good (negative line-count) way.

  core:
   - fix drm_wait_vblank uapi copying bug

  ttm:
   - fix debugfs init when debugfs is off

  amdgpu:
   - vega10 SMU workload fix
   - DCN VM fix
   - DCN 3.01 watermark fix

  amdkfd:
   - SVM fix

  nouveau:
   - ampere display fixes
   - remove MM misfeature to fix a longstanding race condition

  i915:
   - tweaked display workaround for all PCHs
   - eDP MSO pipe sanity for ADL-P fix
   - remove unused symbol export

  mediatek:
   - AAL output size setting
   - Delete component in remove function"
