Subject: [RFC PATCH 07/10] powerpc/mpic: Don't open-code dcr_resource_start
Date: Mon, 31 Oct 2011 17:10:08 -0400 [thread overview]
Message-ID: <1320095411-20667-8-git-send-email-Kyle.D.Moffett@boeing.com> (raw)
In-Reply-To: <1320095411-20667-1-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.
