[d-kernel] [PATCH 29/33] ASoC: codecs: ES8326: suspend issue

[kovalev@altlinux.org]

From: Zhang Yi <zhangyi@everest-semi.com>

We find that we need to disable micbias for the codec to enter suspend
So We modify the trigger conditions for enable_micbias and disable_micbias

(kovalev)
This patch is taken from the mailing list. At the time of application,
this patch was not noticed by the maintainers of the sound subsystem,
but it will happen soon.
