From c51242e7080d2265761de309cdea222d7e27bdfe Mon Sep 17 00:00:00 2001 From: Kyle Moffett Date: Fri, 2 Dec 2011 06:28:06 +0000 Subject: powerpc/mpic: Cache the device-tree node in "struct mpic" Store the node pointer in the MPIC during initialization so that all of the later operational code can just reuse the cached pointer.
