From cf61393f4aa30f4c2a11cf2437d49ff4de6eb4fb Mon Sep 17 00:00:00 2001 From: Pierre Morel Date: Mon, 21 Dec 2015 15:31:06 +0100 Subject: [PATCH] s390/con3270: testing return kzalloc retval Return value from kzalloc is not tested and using a null pointer would lead to crash. Even if this should not happen at this moment, we may let the system decide if there is a better choice.
