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,
