[PATCH 4.4 094/190] wl1251: check return from call to wl1251_acx_arp_ip_filter
From: Greg Kroah-Hartman
Date: Wed Apr 11 2018 - 14:47:50 EST
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
[ Upstream commit ac1181c60822292176ab96912208ec9f9819faf8 ]
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")
