Subject: [PATCH] net: ethernet: mediatek: remove useless code in mtk_probe()
Date: Fri, 7 Jul 2017 15:23:34 -0500	[thread overview]
Message-ID: <20170707202333.GA5114@embeddedgus> (raw)
In-Reply-To: <20170707150831.Horde.MYtEbXeqxGS-hTg2bUv3DWt@gator4166.hostgator.com>

Remove useless local variables _match_, _soc_ and the code related.

Notice that

const struct of_device_id of_mtk_match[] = {
        { .compatible = "mediatek,mt2701-eth" },
        {},
};

So match->data is NULL.
