The platform-drivers-x86 updates were submitted this afternoon for the Linux 4.12 kernel and it's on the heavier side with a lot of new material for benefiting Intel-powered laptops/ultrabooks.

Highlights of the platform-drivers-x86 work for Linux 4.12 include:

- Dell keyboard backlight improvements with the dell-laptop driver adding a keyboard backlight timeout AC setting and other changes.

- The intel-vbtn driver that was recently introduced now has support for volume up and down.

- An Intel Cherry Trail ACPI INT33FE driver was added.

- Many code clean-ups to the hp-wmi and fujitsu-laptop drivers.

- The thinkpad_acpi driver was updated with mappings for new hotkeys. This should benefit at least the ThinkPad T470.
