Merge tag 'platform-drivers-x86-v4.20-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform driver updates from Darren Hart:

 - Move the Dell dcdbas and dell_rbu drivers into platform/drivers/x86
   as they are closely coupled with other drivers in this location.

 - Improve _init* usage for acerhdf and fix some usage issues with
   messages and module parameters.

 - Simplify asus-wmi by calling ACPI/WMI methods directly, eliminating
   workqueue overhead, eliminate double reporting of keyboard backlight.

 - Fix wake from USB failure on Bay Trail devices (intel_int0002_vgpio).

 - Notify intel_telemetry users when IPC1 device is not enabled.

 - Update various drivers with new laptop model IDs.

 - Update several intel drivers to use SPDX identifers and order headers
   alphabetically.
