From b9e8415ffcc25c463a18e179710e1d3f8e281a03 Mon Sep 17 00:00:00 2001 From: Srinivasa Rao Mandadapu Date: Tue, 22 Mar 2022 21:48:57 +0530 Subject: [PATCH] ASoC: codecs: Fix error handling in power domain init and exit handlers [ Upstream commit 1a8ee4cf84187bce17c76886eb6dd9389c3b99a8 ] Update error handling in power domain init and exit handlers, as existing handling may cause issues in device remove function. Use appropriate pm core api for power domain get and sync to avoid redundant code.
