According to stmmac_main.c, the driver may sleep under a spinlock,
and the function call path is:
stmmac_suspend (acquire the spinlock)
stmmac_disable_all_queues
napi_disable
might_sleep --> may sleep
msleep --> may sleep
This bug is found by my static analysis tool and my code review.
Thanks,
Jia-Ju Bai
