Subject: [PATCH 1/2] hwrng: omap - Remove useless test before clk_disable_unprepare
Date: Wed, 28 Feb 2018 15:27:22 +0100	[thread overview]
Message-ID: <20180228142723.11562-2-gregory.clement@bootlin.com> (raw)
In-Reply-To: <20180228142723.11562-1-gregory.clement@bootlin.com>

clk_disable_unprepare() already checks that the clock pointer is valid.
No need to test it before calling it.
