From: Valentine Barshak Date: Mon, 29 Oct 2007 20:29:02 +0000 (+0300) Subject: MTD: small physmap_of partition parsing fixes X-Git-Tag: v2.6.25-rc1~296^2~96 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4edaf56e0f8a6f71e3361bf74e3dc835811761e6;p=linux-2.6 MTD: small physmap_of partition parsing fixes Use of_get_next_child for proper ref counting as suggested by Stephen Rothwell and remove add_mtd_partitions from parse_partitions to avoid duplicate mtd device registration for RedBoot partitions.
