Re: [PATCH RESEND] HID: Stop hiding options with !EXPERT

I can't really comment on the overall situation (Jiri replied to your last

Perhaps the Kconfig for Logitech does need some TLC.

It should be remembered that it supports a wide range of devices from
Unifying, to game controllers and wheels. In total it knows about 30
USB-IDs.

It make sense to remain as a module (if modules are enabled) when 'INPUT=y
and HID=y', and should not force 'FF_MEMLESS=Y' (just leave that as module
too).

There is also the 'LEDS CLASS' which is required for G27 support. IIRC
there was some 'magic' done with hid-steelseries to tweak problems with
LEDs.

I'd be open to helping this happen, given some guidance.
