If you plan do semantic patch then there are also examples of:
./drivers/staging/rtl8712/rtl871x_recv.c:
if (!memcmp(pattrib->bssid, "\x0\x0\x0\x0\x0\x0", ETH_ALEN) |
similarly
is_broadcast_ether_addr() to replace memcmp with 6 off 0xFF
and endless number of memcmp that can be replaced with
ether_addr_equal()
Thanks
