[PATCH] ASoC: wm8962: Fix suspend while playing music

From: Adam Ford
Date: Thu May 26 2022 - 14:22:09 EST


If the audio CODEC is playing sound when the system is suspended,
it can be left in a state which throws the following error:

wm8962 3-001a: ASoC: error at soc_component_read_no_lock on wm8962.3-001a: -16

Once this error has occurred, the audio will not work again until rebooted.

Fix this by configuring SET_SYSTEM_SLEEP_PM_OPS.
