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, Jia-Ju Bai
