[PATCH 06/10] ASoC: SOF: Intel: hda: disable SoundWire interrupts on suspend

From: Pierre-Louis Bossart
Date: Thu Mar 12 2020 - 15:35:00 EST


Doing this avoid conflicts and errors reported on the bus.

The interrupts are only re-enabled on resume after the firmware is
downloaded, so the behavior is not fully symmetric
