According to sound/soc/atmel/atmel_ssc_dai.c, the driver may sleep under a spinlock. The function call path is: atmel_ssc_shutdown (acquire the spinlock) free_irq --> 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.
