Subject: [PATCH] clk: ingenic/TCU: Remove NULL pointer check before clk_enable/disable
Date:   Wed,  4 Nov 2020 07:11:14 +0000
Message-Id: <20201104071114.6322-1-vulab@iscas.ac.cn>
Precedence: bulk

Because clk_enable and clk_disable already checked NULL clock parameter,
so the additional checks are unnecessary, just remove them.
