Modern LG devices like the LG Gram 16T90SP currently do not work
with the lg-laptop driver due to a number of changes inside the
underlying ACPI interface:
- events are now exclusively delivered as native ACPI events, the
legacy WMI interface does not work anymore.
- the "WMAB" control method can return both integers and buffers.
- new events where introduced.
- strict keyboard backlight interface.
The first patch fixes and issue inside the LED resource handling,
while the remaining patches add support for the above changes.
The patches where tested by users on bugzilla
(https://bugzilla.kernel.org/show_bug.cgi?id=218901) and work on
both "old" and "new" LG devices.
