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

From: Zhang Changzhong
Date: Mon Sep 07 2020 - 09:06:35 EST


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