4.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Christophe Jaillet <[email protected]> commit 410280bac6224e066f4cf0b87db08f0418a135b6 upstream. We know that 'retval = 0' because it has been tested a few lines above. So, if 'devm_kmalloc' fails, 0 will be returned instead of an error code. Return -ENOMEM instead.
