[PATCH 0/4] ASoC/soundwire: fix race conditions on remove

[Bard Liao]

There is a possible rate condition when removing the soundwire driver.
When the manager becomes pm_runtime active in the remove procedure,
peripherals will become attached, and do the initialization process.
We have to wait until all the devices are fully resumed before the
cleanup, otherwise there is a possible race condition where asynchronous
workqueues initiate transfers on the bus that cannot complete. This
patchset fixes the issue by ensuring all devices are fully resumed and
SoundWire interrupt is disabled after all jobs are done.
The change is mainly on SoundWire. It would be better to go through
SoundWire tree.

Bard Liao (3):
  soundwire: intel_auxdevice: use pm_runtime_resume() instead of
    pm_request_resume()
  soundwire: intel: export intel_resume_child_device
  soundwire: intel_init: resume all devices on exit.

  ASoC: SOF: Intel: hda: disable SoundWire interrupt later
