If you look at 'Kconfig' every other driver is fragmented into a 'driver'
and 'driver_ff', it is only the 'driver_ff' bit which does the
force-feedback and all the 'drivers' would appear to work OK (as pure
input devices) with FF disabled.

Someone here will be able to comment whether that is policy, convention or
just historic....

600 lines where? What's the other costs to the system when enabling the FF
code in the kernel.

Again I'm not here to kick up a fuss; it just looked different from the
norm, so I was flagging it.
