From ca629928b9d5b28789c4b59729113e9d2b1bc7c0 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 11 May 2011 14:34:53 +0200 Subject: [PATCH] ASoC: Disable WM8994/58 microphone detection over suspend It will be non-functional with the basises and clocks off anyway, if the system needs microphone detection enabled over suspend then it should be causing the CODEC to ignore suspend using the APIs for that to prevent the biases being disabled.
