From 16cf6b804d37e8a0c6e36965d3a2c661b5116141 Mon Sep 17 00:00:00 2001 From: Maithili Hinge Date: Mon, 14 Apr 2014 15:32:49 -0700 Subject: [PATCH] mwifiex: change memset to simple assignment for ht_cap.mcs.rx_mask WARNING: single byte memset is suspicious. Swapped 2nd/3rd argument? This code happens to work because rx_mcs is the first variable in mcs structure. We should use 'mcs.rx_mcs' here anyway.
