From: Sergei Trofimovich
Date: Wed Sep 09 2015 - 16:57:17 EST


From: Sergei Trofimovich <siarheit@xxxxxxxxxx>

Noticed by gcc-5.2.0:

net/mac80211/rate.c: In function 'rate_control_cap_mask':
net/mac80211/rate.c:719:25: warning: 'sizeof' on array function parameter 'mcs_mask' will return size of 'u8 * {aka unsigned char *}' [-Wsizeof-array-argument]
for (i = 0; i < sizeof(mcs_mask); i++)
