[PATCH 0/6] HID: asus: add support for T3304 keyboard

[James Ye <jye836@gmail.com>]

This series adds support for the ASUS Vivobook Slate 13 OLED (T3304)
detachable keyboard. The keyboard is a USB device presenting two
interfaces: keyboard and touchpad. Basic functionality already works
with hid-generic and hid-multitouch, but Fn key chords including media
keys and LEDs do not work.

To add support, bind the keyboard interface to hid-asus. However, the
ASUS-specific report descriptors are on the touchpad interface, so fixup
the descriptor so that hid-asus knows about them. Media keys are also
sent via the touchpad interface, so add MT_CLS_ASUS to this device in
hid-multitouch.

Also included is a fix for a use-after-free in hid-input.c discovered
during development, but technically unrelated to the device.
