Subject: [PATCH] iio: adc: stm32-dfsdm: Remove redundant null check before clk_disable_unprepare
Date: Fri, 18 Dec 2020 09:41:45 +0000 [thread overview]
Message-ID: <20201218094145.1123-1-vulab@iscas.ac.cn> (raw)
ecause clk_disable_unprepare() already checked NULL clock parameter,
so the additional check is unnecessary, just remove it.
