Subject: [PATCH 3.18 039/121] block: fix an error code in add_partition()

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>


[ Upstream commit 7bd897cfce1eb373892d35d7f73201b0f9b221c4 ]

We don't set an error code on this path.  It means that we return NULL
instead of an error pointer and the caller does a NULL dereference.

Fixes: 6d1d8050b4bc ("block, partition: add partition_meta_info to hd_struct")
