[PATCH 1/2] Asoc: qcom: lpass-cpu: Fix clock disable failure

From: Srinivasa Rao Mandadapu
Date: Tue Oct 13 2020 - 09:40:26 EST


From: V Sujith Kumar Reddy <vsujithk@xxxxxxxxxxxxxx>

Disable MI2S bit clock from PAUSE/STOP/SUSPEND usecase
instead of shutdown time. Acheive this by invoking
clk_disable_unprepare API from cpu daiops shutdown to
cpu daiops trigger.
This Fix is update to the below patch.
