Subject: [PATCH 5/8] of: When checking for existing devices also check resource end
Date: Mon, 20 May 2013 16:14:17 +0200 [thread overview]
Message-ID: <1369059260-28872-6-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1369059260-28872-1-git-send-email-s.hauer@pengutronix.de>
When registering devices from the devicetree we check if these
devices already exist. When doing this not only check the resource
start but also the resource end.
This helps with the probing of simple buses for which child nodes
often begin at the very same address as the parents.
