From 40f02cd9f21dc2bd2c65713eb986139bb1ea0363 Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Mon, 6 Feb 2012 16:05:14 +0000 Subject: [PATCH] ASoC: dapm: Export mixer|mux_update_power() to public API. Allow for the operation of custom mixer and mux DAPM widgets that can call snd_soc_dapm_mixer_update_power() and snd_soc_dapm_mux_update_power() directly after updating their status. This is useful with complex DAPM Mixer operations where we need to do additional work in addition to setting a few mixer register bits.
