- Convert "options EVDEV" to "device evdev" and "device uinput", add
modules for both new devices. They are isolated subsystems and do not
require any compile-time changes to general kernel subsytems
- For hybrid drivers that have evdev as an optional way to deliver input
events add option EVDEV_SUPPORT. Update all existing hybrid drivers
to use it instead of EVDEV
- Remove no-op DECLARE_MODULE in evdev, it's not required, MODULE_VERSION
is enough
- Add evdev module dependency to uinput

evdev is a generic input event interface compatible with Linux
evdev API at ioctl level. It allows using unmodified (apart from
header name) input evdev drivers in Xorg, Wayland, Qt.
This commit has only generic kernel API. evdev support for individual
hardware drivers like ukbd, ums, atkbd, etc. will be committed later.
Project was started by Jakub Klama as part of GSoC 2014. Jakub's
evdev implementation was later used as a base, updated and finished
by Vladimir Kondratiev.
