Subject: [PATCH 15/15] powerpc: law: use signed type to allow error checking
Date: Mon, 17 May 2021 20:54:24 +0200	[thread overview]
Message-ID: <20210517185424.32145-16-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210517185424.32145-1-s.hauer@pengutronix.de>

unsigned idx is checked for >= 0 which is always true and < 0 which is
never true. Use a signed type instead.
