Subject: [PATCH 5/5] sh_eth: Remove goto statements that jump straight to a return
Date: Thu, 20 Mar 2014 13:59:02 +0000	[thread overview]
Message-ID: <1395324035-22918-6-git-send-email-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <1395324035-22918-1-git-send-email-laurent.pinchart+renesas@ideasonboard.com>

"goto" is well accepted for error paths in the kernel but should not be
used unnecessarily. Return the correct value directly instead of using a
goto when possible.
