4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Stefan Schmidt <stefan@xxxxxxxxxxxxxxxxxx> [ Upstream commit 20f330452ad8814f2289a589baf65e21270879a7 ] The check is valid but it does not warrant to crash the kernel. A WARN_ON() is good enough here. Found by checkpatch.
