Subject: [PATCH 02/14] xen: events: fix xen_map_pirq_gsi error return
Date: Thu, 10 Mar 2011 16:08:03 +0000	[thread overview]
Message-ID: <1299773295-348-2-git-send-email-ian.campbell@citrix.com> (raw)
In-Reply-To: <1299773279.17339.813.camel@zakaz.uk.xensource.com>

Fix initial value of irq so that first goto out (if pirq or gsi
arguments are too large) actually returns an error.

Signed-off-by: Ian Campbell <ian.campbell@citrix.com>
