Commit d74bcaaeb6682 (ASoC: wm5102: Move ultrasonic response settings lock to the driver level) created a driver local mutex for protecting the ultrasonic response settings but neglected to initialize that mutex, causing loud complaints from lockep and potential runtime failures. Fix this by initializing the mutex. Signed-off-by: Mark Brown <broonie@kernel.org> --- sound/soc/codecs/wm5102.c | 2 ++ 1 file changed, 2 insertions(+)
