[ALSA] at73c213: replace spinlock in mixer functions with a mutex
This patch fixes the locking bug in the at73c213 SPI sound driver. This bug was triggered because spinlocks were wrapped around the spi_sync call which might sleep. The fix was to add a mutex to the sound driver and replace the spinlocks in the mixer functions with mutex lock/unlock. Tested on STK1000/STK1002.
