Subject: [PATCH V4 10/16] irqchip: crossbar: Change the goto naming
Date: Thu, 26 Jun 2014 12:40:28 +0530	[thread overview]
Message-ID: <1403766634-18543-11-git-send-email-r.sricharan@ti.com> (raw)
In-Reply-To: <1403766634-18543-1-git-send-email-r.sricharan@ti.com>

From: Nishanth Menon <nm@ti.com>

Using err1,2,3,4 etc makes it hard to ensure a new exit path in the
middle will not result in spurious changes, so rename the error paths
as per the function it does.
