From 45cee4f594bcb3083c2d8475462af2f2ddf29aff Mon Sep 17 00:00:00 2001 From: Fabian Frederick Date: Fri, 20 Feb 2015 19:12:52 +0100 Subject: [PATCH] mISDN: replace current->state by set_current_state() Use helper function to access current->state. Direct assignments are prone to races and therefore buggy. Thanks to Peter Zijlstra for the exact definition of the problem. Signed-off-by: Fabian Frederick Signed-off-by: David S.
