Subject: clk: rockchip: Remove redundant null check before clk_prepare_enable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7f5b57a095f3b9532793d143655e83433bb448af;p=linux.git

clk: rockchip: Remove redundant null check before clk_prepare_enable

Because clk_prepare_enable() already checked NULL clock parameter,
so the additional check is unnecessary, just remove it.
