PM / sleep: Show freezing tasks that caused a suspend abort
For debug purposes it would be nice to see which tasks caused a suspend abort, i.e. which tasks were still in the process of freezing when a wakeup event occurred. This patch adds the info to pm_debug_messages. Signed-off-by: Todd Brandt <todd.e.brandt@linux.intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
