Subject: [PATCH net-next 3/6] net: stmmac: xgmac: Reinitialize correctly a variable
Date: Tue, 10 Sep 2019 16:41:24 +0200
Message-ID: <cc78134084a4d7c4f2ea35e369c422b71209d021.1568126224.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1568126224.git.joabreu@synopsys.com>
In-Reply-To: <cover.1568126224.git.joabreu@synopsys.com>

'value' was being or'ed with a value from another register. This is a
typo and could cause new written value to be wrong. Fix it.
