[alsa-devel] [PATCH] ASoC: codecs: rt5682: initialize mutex before using

From: Xun Zhang <xun2.zhang at intel.com>
In rt5682 codec driver, a mutex called "calibrate_mutex" is used
in rt5682_calibrate() before initialization, which causes warning
in lock debug. Move the initialization before the usage of mutex.
