Subject: [PATCH 5.18 0849/1095] ASoC: samsung: change gpiod_speaker_power and rx1950_audio from global to static variables

From: Tom Rix <trix@...hat.com>

[ 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.
