Merge tag 'acpi-4.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"Two fixes for problems introduced recently (ACPICA and the ACPI
backlight driver) and one fix for an older issue that prevents at
least one system from booting.
Specifics:
- Fix an incorrect check introduced by recent ACPICA changes which
causes problems with booting KVM guests to happen, among other
things (Lv Zheng).
- Fix a backlight issue introduced by recent changes to the ACPI
video driver (Aaron Lu).
- Fix the ACPI processor initialization which attempts to register an
IO region without checking if that really is necessary and
sometimes prevents drivers loaded subsequently from registering
their resources which leads to boot issues (Rafael Wysocki)"
* tag 'acpi-4.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI / processor: Avoid reserving IO regions too early
ACPICA / Hardware: Fix old register check in acpi_hw_get_access_bit_width()
ACPI / Thermal / video: fix max_level incorrect value
