Subject: [PATCH] drm/msm: Remove redundant null check
Date: Mon, 19 Oct 2020 14:04:22 +0800	[thread overview]
Message-ID: <1603087462-37505-1-git-send-email-tiantao6@hisilicon.com> (raw)

clk_prepare_enable() and clk_disable_unprepare() will check
NULL clock parameter, so It is not necessary to add additional checks.
