component has io_mutex, but it had been used at snd_soc_component_update_bits_legacy() only which does read and write.
this is quite interesting. I wonder as regmap does its own locking, should io_mutex only be used on the non-regmap paths? The patch looks correct though, holding the mutex only in update_bits won't help when write is without locks.
