[BUG] wl3501: a possible sleep-in-atomic bug in wl3501_reset

[Jia-Ju Bai <baijiaju1990@xxxxxxxxx>]

According to drivers/net/wireless/wl3501_cs.c, the driver may sleep 
under a spinlock.
The function call path is:
wl3501_reset (acquire the spinlock)
  free_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
