From b3b73ec0d7fe5bf8f950232aa58dfa0416a62372 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 26 Dec 2011 00:29:55 +0100 Subject: [PATCH] PM / Freezer: fix return value of freezable_schedule_timeout_killable() ...it should return the return code from schedule_timeout_killable(), not the one from freezer_count(). All of the current callers ignore the return code so the bug is harmless but it's worth fixing. Signed-off-by: Jeff Layton Signed-off-by: Rafael J.
