For input I want to do some actions every time I connect a new
interface to the device and I want to have it done in core. So when a
new interface registers core installs add()/remove() handler which
then calls interface's connect/disconnect handlers. The other way
around would be to program every interface to call into input-core
exported function to finalize connect/disconnect which is not clean
IMHO. I generally prefer the core to control the operation, instead of
leaving it to individual drivers.
