From: Boris BREZILLON <boris.brezillon@xxxxxxxxxxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit e5bae86797141e4a95e42d825f737cb36d7b8c37 upstream.
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.
