Subject: [PATCH 1/7] mwifiex: change memset to simple assignment for ht_cap.mcs.rx_mask
Date: Mon, 14 Apr 2014 15:32:49 -0700	[thread overview]
Message-ID: <1397514775-4777-1-git-send-email-bzhao@marvell.com> (raw)

From: Maithili Hinge <maithili@marvell.com>

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.
