Subject: Freezer: remove redundant check in try_to_freeze_tasks
From: Rafael J. Wysocki <rjw@xxxxxxx>
We don't need to check if todo is positive before calling time_after() in
try_to_freeze_tasks(), because if todo is zero at this point, the loop will be
broken anyway due to the while () condition being false.
