commit 86686c6e2f7c6f0944bced11550e06d20bc6957f (HEAD, upstream/master)
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Sep 3 09:50:05 2018 +0100

    igt/pm_backlight: Skip if pm is not supported
    
    If we cannot do runtime suspend, testing it's impact on the backlight is
    moot. Simply skip on systems that cannot runtime suspend.
