[PATCH 2/2] ASoC: codecs: soundwire: call pm_runtime_resume() in component probe

Pierre-Louis Bossart pierre-louis.bossart at linux.intel.com
Thu Jun 16 23:08:25 CEST 2022


Make sure that the bus and codecs are pm_runtime active when the card
is registered/created. This avoid timeouts when accessing registers.
