According to sound/soc/sti/uniperif_player.c, the driver may sleep under a spinlock. The function call path is: uni_player_ctl_iec958_put (acquire the spinlock) uni_player_set_channel_status mutex_lock --> may sleep
I do not find a good way to fix it, so I only report. This possible bug is found by my static analysis tool (DSAC) and checked by my code review.
Thanks, Jia-Ju Bai
