Subject: [PATCH] i2c: mediatek: remove redundant null check
Date: Wed, 30 Sep 2020 08:42:33 +0000 [thread overview]
Message-ID: <20200930084233.53085-1-vulab@iscas.ac.cn> (raw)
Because clk_disable_unprepare already checked NULL clock parameter,
so the additional checks are unnecessary, just remove it
