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. * tag 'platform-drivers-x86-v4.20-1' of git://git.infradead.org/linux-platform-drivers-x86: (64 commits) HID: asus: only support backlight when it's not driven by WMI platform/x86: asus-wmi: export function for evaluating WMI methods platform/x86: asus-wmi: Only notify kbd LED hw_change by fn-key pressed platform/x86: wmi: declare device_type structure as constant platform/x86: ideapad: Add Y530-15ICH to no_hw_rfkill platform/x86: Add Intel AtomISP2 dummy / power-management driver platform/x86: touchscreen_dmi: Add min-x and min-y settings for various models platform/x86: touchscreen_dmi: Add info for the Onda V80 Plus v3 tablet platform/x86: touchscreen_dmi: Add info for the Trekstor Primetab T13B tablet platform/x86: intel_telemetry: Get rid of custom macro platform/x86: intel_telemetry: report debugfs failure MAINTAINERS: intel_telemetry: Update maintainers info platform/x86: Add LG Gram laptop special features driver platform/x86: asus-wmi: Simplify the keyboard brightness updating process platform/x86: touchscreen_dmi: Add info for the Trekstor Primebook C11 convertible platform/x86: mlx-platform: Properly use mlxplat_mlxcpld_msn201x_items MAINTAINERS: intel_pmc_core: Update MAINTAINERS firmware: dcdbas: include linux/io.h platform/x86: intel-wmi-thunderbolt: Add dynamic debugging platform/x86: intel-wmi-thunderbolt: Convert to use SPDX identifier ...
