[alsa-devel] [BUG] haswell: a possible sleep-in-atomic bug in hsw_irq_thread

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
