4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe Jaillet <christophe.jaillet@wanadoo.fr>
commit af48d7bc3756a0cd882d65bff14ab39746ba57fe upstream.
We know that 'ret = 0' because it has been tested a few lines above. So, if 'kzalloc' fails, 0 will be returned instead of an error code. Return -ENOMEM instead.
