As far as I can see, in practice, you only move up { from the line below.

This was done using the following semantic patch by coccinelle,
except kfree((unsigned char*) pcmd->parmbuf) which was transformed by
hand because coccinelle didn't have enough type information.

The driver may sleep under a spinlock, and the function call path is:
rtw_set_802_11_bssid(acquire the spinlock)
rtw_disassoc_cmd
kzalloc(GFP_KERNEL) --> may sleep
To fix it, GFP_KERNEL is replaced with GFP_ATOMIC.
This bug is found by my static analysis tool and my code review.
