[PATCH] ACPI/PAD: power_saving_thread() is not freezable

From: Jiri Kosina
Date: Sun Oct 25 2015 - 23:02:43 EST


From: Jiri Kosina <jkosina@xxxxxxx>

power_saving_thread() calls try_to_freeze(), but the thread doesn't mark
itself freezable through set_freezable(), so the try_to_freeze()
call is useless.
