Subject: [PATCH 19/23] include: bitops: fix dead increment in fls() and ffs()
Date: Mon, 11 May 2020 09:21:36 +0200 [thread overview]
Message-ID: <20200511072140.29610-20-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200511072140.29610-1-a.fatoum@pengutronix.de>
Static analyzers trip over this and a comment is as descriptive,
thus replace the dead code.
