From 5a6ea4af0907f995dc06df21a9c9ef764c7cd3bc Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Tue, 25 Sep 2012 15:27:13 +0530 Subject: [PATCH] mtd: ofpart: Fix incorrect NULL check in parse_ofoldpart_partitions() The pointer returned by kzalloc should be tested for NULL to avoid potential NULL pointer dereference later. Incorrect pointer was being tested for NULL. Bug introduced by commit fbcf62a3 (mtd: physmap_of: move parse_obsolete_partitions to become separate parser). This patch fixes this bug.
