From cb08e0353c249a27aed10c6f60a13871ae449d33 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 23 Jul 2017 00:03:43 +0200 Subject: PM / timekeeping: Print debug messages when requested The messages printed by tk_debug_account_sleep_time() are basically useful for system sleep debugging, so print them only when the other debug messages from the core suspend/hibernate code are enabled. While at it, make it clear that the messages from tk_debug_account_sleep_time() are about timekeeping suspend duration, because in general timekeeping may be suspeded and resumed for multiple times during one system suspend-resume cycle.
