Subject: [PATCH] hwrng: fix simple_return.cocci warnings
Date: Sun, 4 Oct 2015 05:02:30 +0800 [thread overview]
Message-ID: <20151003210230.GA71026@lkp-hsx03> (raw)
In-Reply-To: <1443904519-24012-3-git-send-email-daniel.thompson@linaro.org>
drivers/char/hw_random/stm32-rng.c:164:1-4: WARNING: end returns can be simpified
Simplify a trivial if-return sequence. Possibly combine with a
preceding function call.
