Hallyn" , Stephen Smalley , William Roberts Cc: LKML , kernel-janitors@vger.kernel.org From: Markus Elfring Date: Sun, 15 Jan 2017 12:40:35 +0100 One local variable was set to an error code in two cases before a concrete error situation was detected. Thus move the corresponding assignments into if branches to indicate a software failure there.
