[alsa-devel] [PATCH 2/2] ASoC: wm9705: Remove ac97_read/ac97_write wrappers

[Lars-Peter Clausen]

Since the regmap conversion ac97_read/ac97_write are just simple wrappers
around snd_soc_read/snd_soc_write. Use those instead directly and remove
the wrappers.

Also use snd_soc_update_bits() where appropriate.
