Subject: [PATCH 07/10] powerpc/mpic: Don't open-code dcr_resource_start
Date: Tue, 29 Nov 2011 13:58:34 -0500 [thread overview]
Message-ID: <1322593117-29938-8-git-send-email-Kyle.D.Moffett@boeing.com> (raw)
In-Reply-To: <1322593117-29938-1-git-send-email-Kyle.D.Moffett@boeing.com>
Don't open-code the OpenFirmware "dcr-reg" property lookup trying to map
DCR resources. This makes the code a bit easier to read.
