According to sound/soc/intel/haswell/sst-haswell-ipc.c, the driver may
sleep under a spinlock.
The function call path is:
hsw_irq_thread (acquire the spinlock)
hsw_process_notification
hsw_log_message
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,
