However, this function is called from the upper ALSA\ncore function snd_ctl_elem_write(), which already holds the write lock on\ncontrols_rwsem for the whole put operation. So there is no need to simply\nhold the lock for fsl_xcvr_activate_ctl() again.\n\nAcquiring the read lock while holding the write lock in the same thread\nresults in a deadlock and a hung task, as reported by Alexander Stein.",
