From: Gregory CLEMENT Date: Wed, 28 Feb 2018 14:27:22 +0000 (+0100) Subject: hwrng: omap - Remove useless test before clk_disable_unprepare X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=10bc320bc9d7f335651c7740b1c6034ba4bfc4f4;p=linux.git hwrng: omap - Remove useless test before clk_disable_unprepare clk_disable_unprepare() already checks that the clock pointer is valid. No need to test it before calling it.
