Subject: [PATCH 3/4] ASoC: wm8971: Use snd_soc_update_bits for read-modify-write
Date: Tue, 04 Oct 2011 09:58:28 +0800 [thread overview]
Message-ID: <1317693508.2688.5.camel@phoenix> (raw)
In-Reply-To: <1317693345.2688.1.camel@phoenix>
Use snd_soc_update_bits for read-modify-write register access instead of
open-coding it using snd_soc_read and snd_soc_write
