From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Sat, 21 Jan 2017 16:10:50 +0100 * Return directly after a call of the function "__copy_from_user" failed here. This issue was detected by using the Coccinelle software. * Delete the jump label "out2" which became unnecessary with this refactoring.
