Subject[PATCH] ASoC: samsung: change gpiod_speaker_power and rx1950_audio from global to static variables
Date
sparse reports
sound/soc/samsung/rx1950_uda1380.c:131:18: warning: symbol 'gpiod_speaker_power' was not declared. Should it be static?
sound/soc/samsung/rx1950_uda1380.c:231:24: warning: symbol 'rx1950_audio' was not declared. Should it be static?

Both gpiod_speaker_power and rx1950_audio are only used in rx1950_uda1380.c,
so their storage class specifiers should be static.

Fixes: 83d74e354200 ("ASoC: samsung: rx1950: turn into platform driver")
