From: Gavin Shan Date: Thu, 26 Dec 2013 01:29:40 +0000 (+0800) Subject: powerpc/powernv: Remove unnecessary assignment X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8184616f6fcfc98f0ebf083cbf6a43e5efe54e8a;p=openwrt%2Fstaging%2Fblogic.git powerpc/powernv: Remove unnecessary assignment We don't have IO ports on PHB3 and the assignment of variable "iomap_off" on PHB3 is meaningless. The patch just removes the unnecessary assignment to the variable. The code change should have been part of commit c35d2a8c ("powerpc/powernv: Needn't IO segment map for PHB3").
