Title:
Brightness hotkey broken on UX302LG

Status in linux package in Ubuntu:
Incomplete

Bug description:
Brightness control key is broken on UX302LG laptop.

Other hotkeys work (as per Bug #1270661) .

Soft control works and is able to dim screen brightness.

- Key does not output anything using xev.
- Nothing shows up using acpi_listen when pressing the key.

Tried acpi_type=vendor with no luck.

From discussions I had, next step would probably be to dump DSDT from
/proc and try to recompile them with the Intel ASL compiler that could
indicate where problem lies, fix the error and use that specific blob
at boot time.
