The driver may sleep under a spinlock. The function call path is: snd_cx88_switch_put (acquire the spinlock) v4l2_ctrl_find 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
