Right now, the gpio-keys driver is mostly used with EV_KEY event types.
However, this driver (and its devicetree bindings) support specifying
a different input type, like EV_ABS, even though this doesn't work in
practice: "key pressed" events are correctly received and treated, but
"key released" are silently ignored.
With this commit, keys configured as EV_ABS will inject an event with
the value 0 when released.
