Subject: [BUG] atlx: a possible sleep-in-atomic bug in atl1_intr
Date: Wed, 13 Dec 2017 18:07:53 +0800	[thread overview]
Message-ID: <d9660caa-3873-b99d-c967-8e139d2a96da@gmail.com> (raw)

The driver may sleep in the interrupt handler.
The function call path is:
atl1_intr (interrupt handler)
   atlx_irq_disable
     synchronize_irq --> 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
