Subject: acpi: enable GPEs before calling _WAK on resume
From: Thomas Renninger <trenn@xxxxxxx>
It seems it's required to enable GPEs before _WAK. E.g. X60 triggers a
LID related GPE instead of doing a Notify in WAK. Now the GPE reaches the
kernel and the Notify for LID status change gets thrown from there.
