The driver may sleep under a spinlock.
The function call path is:
update_beacon (acquire the spinlock)
update_BCNTIM
set_tx_beacon_cmd
kzalloc(GFP_KERNEL) --> may sleep
kmemdup(GFP_KERNEL) --> may sleep
To fix it, GFP_KERNEL is replaced with GFP_ATOMIC.
This bug is found by my static analysis tool(DSAC) and checked by my code review.
