[PATCH 1/2] HID: multitouch: do not filter mice nodes

From: Benjamin Tissoires
Date: Mon Aug 12 2019 - 12:23:37 EST


It was a good idea at the time to not create a mouse node for the
multitouch touchscreens, but:
- touchscreens following the Win 8 protocol should not have this
disturbing mouse node anymore, or if they have, it should be
used for something else (like a joystick attached to the screen)
- touchpads have it, and they should not use it unless there is a bug,
but when the laptop has a trackstick, the data are reported through this
mouse node.

So instead of whitelisting all of the devices that have a need for the
mouse node, just export it.
hid-input.c will append a suffix to it ('Mouse'), so users will eventually
see if something goes wrong.
