commit 534e465845ebfb4a97eb5459d3931a0b35e3b9a5 upstream.
This reverts commit b26cd9325be4c1fcd331b77f10acb627c560d4d7.
This patch introduces a regression on Lenovo Z13, which can't wake
from the lid with it applied; and some unspecified AMD based Dell
platforms are unable to wake from hitting the power button
