Subject: [PATCH] staging: rtl8188eu: fix HighestRate check in odm_ARFBRefresh_8188E()
Date:   Thu, 26 Sep 2019 10:31:38 +0300
Message-Id: <20190926073138.12109-1-efremov@linux.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

It's incorrect to compare HighestRate with 0x0b twice in the following
manner "if (HighestRate > 0x0b) ... else if (HighestRate > 0x0b) ...". The
"else if" branch is constantly false. The second comparision should be
with 0x03 according to the max_rate_idx in ODM_RAInfo_Init().
