From 17b536cc43bcf2afcc20b4812f93a895881b5f4f Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Fri, 6 Mar 2009 20:01:08 +0900 Subject: [MTD] mtdpart: Make all partition parsers return allocated array Currently redboot and afx parser return allocated mtd_partition array and cmdlinepart and ar7 return persistent array. This patch make cmdlinepart and ar7 also return allocated array, so that all users can free it regardless of parser type.
