[PATCH net-next] net: ethernet: fec: remove redundant null check before clk_disable_unprepare()

From: Zhang Changzhong
Date: Mon Sep 07 2020 - 08:53:06 EST


Because clk_prepare_enable() and clk_disable_unprepare() already checked
NULL clock parameter, so the additional checks are unnecessary, just
remove them.
