Input: HID - add a quirk for the Logitech USB Receiver
Logitech USB Receiver (046d:c101) has two interfaces. The first one
contains fields from HID_UP_KEYBOARD and HID_UP_LED, and the other one
contains fields from HID_UP_CONSUMER and HID_UP_LOGIVENDOR. This device
is used with multiple wireless Logitech products, including UltraX Media
Remote.
All fields on both interfaces are either keys or leds. All fields in the
first interface are marked as Absolute, while the fields in the second
interface are marked as Relative. Marking the keys as relative causes
hidinput_hid_event() to send release events right after key press
events.
The device has EV_REP set, so the userspace expects the device to send
repeat events if a key is held down. However, as hidinput_hid_event()
sends release events immediately, repeat events are not sent at all. In
fact, the userspace has no way of knowing if a key is being held down.
Fix this by adding a quirk for 046d:c101 which changes relative keys to
absolute ones.
