Subject: [PATCH] drm: bridge: adv7511: Remove redundant null check before clk_disable_unprepare
Date: Fri, 27 Nov 2020 09:18:29 +0000 [thread overview]
Message-ID: <20201127091829.50695-1-vulab@iscas.ac.cn> (raw)
Because clk_disable_unprepare() already checked NULL clock parameter,
so the additional check is unnecessary, just remove them.
