A number of upcoming notebook computer designs drive the internal

This EC-based backlight control can be plumbed through to an ACPI
"WMAA" method interface, which in turn can be wrapped by WMI with
the GUID handle 603E9613-EF25-4338-A3D0-C46177516DB7.
Add a new driver, aliased to the WMAA WMI GUID, to expose a sysfs
backlight class driver to control backlight levels on systems with
EC-driven backlights.

Seems like missed Co-developed-by. Or you are the wrong author. Fix accordingly.
I wrote the initial version of this driver that we used internally for
testing, but Daniel almost completely rewrote it for upstreaming. I'd be
fine with just dropping me from the patch entirely and listing Daniel as
the author since it looks almost nothing like the code I wrote.
