[PATCH 6.8 162/273] ASoC: rt722-sdca-sdw: fix locking sequence

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

[ Upstream commit adb354bbc231b23d3a05163ce35c1d598512ff64 ]

The disable_irq_lock protects the 'disable_irq' value, we need to lock
before testing it.
