Subject: ASoC: Ensure we reconfigure WM8958 microphone detection on rate changes
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=52ac7ab2475da2b577e4a4616c98b5d1fa3a3cfd;p=~shefty%2Frdma-dev.git

ASoC: Ensure we reconfigure WM8958 microphone detection on rate changes

We don't need to rerun DAPM if the clock source is the same but we do
need to adjust the microphone detection rate in case we are moving from
an audio to a non-audio rate.
