Subject: [PATCH 3/8] ASoC: SOF: Intel: mtl: factor interrupt enable/disable interrupt functions
From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>
The offsets and sequences are identical for interrupt enabling and
disabling, we can refactor the code with a single routine and a
boolean.
