The ITE8595 keyboard uses the HID_GD_RFKILL_BTN usage code
from the Wireless Radio Controls Application Collection Microsoft
has defined for Windows 8 and later.

However it has a quirk, when the rfkill hotkey is pressed it does
generate a report for the collection, but the reported value is
always 0. Luckily it is the only button in this collection / report,
and it sends a report on release only, so receiving a report means the
button was pressed.

This commit adds a hid-ite driver which watches for the Wireless Radio
Controls Application Collection report and then reports a KEY_RFKILL event,
ignoring the value, making the rfkill on this keyboard work.

Before commits a1cbda7a65a7a ("HID: asus: drop dependency

aforementioned commits expanded this support to other ASUS

In order to clarify that existing keyboard and touchpad quirks
only apply to the I2C devices, and not ASUS keyboards in
general, I2C HID IDs and their corresponding quirk sets have
been renamed. In addition, the latter commit introduced
special key handling, which also applies to the I2C keyboard,
not just Republic of Gamers series. Therefore, the

The LG Melfas touchscreen has a bad firmware where it declares the Contact ID
field as constant while it shouldn't. This messes up the autodetection and the
reporting of the events by hid-multitouch given that hid-input ignores constant
fields.

The autodetection is simply worked around by manually adding the device to
hid_have_special_driver[].

The processing of the events requires either a report fixup, or some specific
case handling. Given that the report fixup would require to basically rewrite
all the report descriptor, I went for the programatic way of fixing that after
the report descriptors are loaded.
