HID: Report usage codes of keys as EV_MSC scancode events
Current HID layer does not report usage codes to the input layer. This
feature
was previously removed, because it caused unnecessary storm of events in
cases
of positioning devices, etc.
This patch adds reporting of usage codes as EV_MSC events only for key
events.
We issue the EV_MSC event only if the state of the key corresponding to the
given code has changed, so that we don't report usages that are sent in
every
report even if the state hasn't changed (for example Shift/Caps Lock/...
states as sent by various keyboards).
This functionality is required at least by KeyTouch in order to provide
convenient means for remapping the usage codes.
