Date: Mon, 7 Sep 2020 20:49:44 +0800 From: Zhang Changzhong <zhangchangzhong@...wei.com> To: <fugang.duan@....com>, <davem@...emloft.net>, <kuba@...nel.org> CC: <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH net-next] net: ethernet: fec: remove redundant null check before clk_disable_unprepare() Because clk_prepare_enable() and clk_disable_unprepare() already checked NULL clock parameter, so the additional checks are unnecessary, just remove them.
