[alsa-devel] [PATCH 13/18] soundwire: intel: disable pm_runtime when removing a master

[Pierre-Louis Bossart]

Prevent race conditions between remove and resume by disabling
pm_runtime.

Note that this only takes care of pm_runtime at the Master level, the
same precautions are needed when removing a Slave device.
