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. The following is an automated git shortlog grouped by driver: Add Intel AtomISP2 dummy / power-management driver: - Add Intel AtomISP2 dummy / power-management driver lg-laptop: - Add LG Gram laptop special features driver HID: -
