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


From: Christophe JAILLET <christophe.jail...@wanadoo.fr>

[ Upstream commit 5c9afbda911ce20b3f2181d1e440a0222e1027dd ]

If the last test in 'ioat_dma_self_test()' fails, we must release all
the allocated resources and not just part of them.
