From fa1a51f3cd9849fcfb811c7cd62d6e2028ad4ea9 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Sun, 1 Nov 2015 20:23:40 +0100 Subject: [PATCH] ASoC: wm9713: use snd_soc_*() calls to update ac97 registers Convert wm9713 to use the more modern registers manipulation functions, such as snd_soc_read(), snd_soc_write() and snd_soc_update_bits().
