Subject: [PATCH v2 2/9] net: stmmac: Stop PHY and remove TX timer on error
Date: Fri, 10 Mar 2017 17:34:54 +0100 [thread overview]
Message-ID: <20170310163501.31811-3-thierry.reding@gmail.com> (raw)
In-Reply-To: <20170310163501.31811-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
If an error occurs while opening the device, make sure that both the TX
timer and the PHY are properly cleaned up.
