[PATCH 3.16 099/410] wl1251: check return from call to wl1251_acx_arp_ip_filter

[Ben Hutchings]

3.16.57-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

commit ac1181c60822292176ab96912208ec9f9819faf8 upstream.

Currently the less than zero error check on ret is incorrect
as it is checking a far earlier ret assignment rather than the
return from the call to wl1251_acx_arp_ip_filter. Fix this by
adding in the missing assginment.

Detected by CoverityScan, CID#1164835 ("Logically dead code")

Fixes: 204cc5c44fb6 ("wl1251: implement hardware ARP filtering")
