Subject[BUG] haswell: A possible sleep-in-atomic bug in hsw_irq_thread
Date
According to sst-haswell-ipc.c, the driver may sleep under a spinlock,
and the function call path is:
hsw_irq_thread (acquire the spinlock)
hsw_process_notification
hsw_log_message
mutex_lock --> may sleep

This bug is found by my static analysis tool and my code review.


Thanks,
Jia-Ju Bai
