[PATCH 0/2] Input: cros-ec-keyb: Don't register keyboard if doesn't exist

[Stephen Boyd]

We're registering a keyboard input device on detachable chromebooks when
that input device doesn't generate any events. This patch series stops
doing that to save some runtime memory and to help userspace understand
that there really isn't a keyboard present when the keyboard is
detached. The second patch is an RFC because it should be picked up
through arm-soc tree, not input tree.
