--------------------------------
[ Upstream commit d2294461b90e0c5b3bbfaaf2c8baff4fd3e2bb13 ]
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.
