[alsa-devel] [PATCH 3/7] ASoC: wm8903: generalize GPIO control register bits

Vladimir Zapolskiy vz at mleia.com
Tue Jun 2 01:09:14 CEST 2015


All GPIO1/2/3/4/5 control registers have the same bit map, but in
implementation of gpiolib callbacks WM8903_GPn_*, WM8903_GP1_* and
WM8903_GP2_* macro are mixed up. Replace particular GPIOn control
register bit definitions with generic ones and save ~150 LoCs.

No functional change.
