From e5bae86797141e4a95e42d825f737cb36d7b8c37 Mon Sep 17 00:00:00 2001 From: Boris BREZILLON Date: Thu, 30 Jul 2015 12:18:03 +0200 Subject: [PATCH] mtd: mtdpart: fix add_mtd_partitions error path If we fail to allocate a partition structure in the middle of the partition creation process, the already allocated partitions are never removed, which means they are still present in the partition list and their resources are never freed.
