You are missing a proper title, and FWIW, b4 doesn't recognize this as a
patch.
synonym reports: "The dock (USB 0b05:182f) reports brightness on the ASUS
vendor usage page 0xff31, usages 0x10 and 0x20, which hid-asus already maps to
KEY_BRIGHTNESSDOWN / KEY_BRIGHTNESSUP. Because the device is not in
asus_devices[], it is claimed by hid-generic, which ignores the vendor page
entirely, so Fn+F5 and Fn+F6 produce no input events at all - not even a
scancode. Keys on the standard consumer page (volume) on the same device work
fine, which makes this look like a backlight or ACPI problem rather than a HID
one."
Add the device ID.

Anyway, feel free to push it to for-7.4/hid-asus with my:
