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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
