Pull ACPI fixes from Rafael Wysocki:
"These fix a recent ACPICA regression affecting control method
execution at the table level and an earlier hibernation regression in
the ACPI driver for Intel SoCs (LPSS) that was missed by a previous
fix in this cycle.
Specifics:
- Fix a recent ACPICA regression introduced by a previous fix that
caused control method execution at the table level to be mishandled
by mistake (Erik Schmauss).
- Fix a hibernation regression from the 4.15 cycle in the ACPI driver
for Intel SoCs (LPSS) that caused the platform firmware to be
confused during resume from hibernation by the driver's PM quirks
which was fixed for system-wide suspend/resume (ACPI S3) earlier in
this cycle, but that previous fix missed the hibernation (ACPI S4)
case (Rafael Wysocki)"
