From 2d4cdd6fc974716555fcbaf7ec1d4dda22784c1b Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Mon, 17 May 2010 14:21:46 +0300 Subject: [PATCH] ASoC: tlv320dac33: Avoid powering off while in BIAS_OFF Avoid calling the dac33_hard_power when the codec was already in BIAS_OFF state. This could happen in device suspend and module removal time.
