Hi Benjamin,
sorry for not responding sooner.
Yes, I have to say I find HID_GROUP_HAVE_SPECIAL_DRIVER very disgusting.
Especially its (non-)relation to hid_have_special_driver[] is very
confusing.
If you could update this to be RMI-specific (i.e. create a special
HID_GROUP for RMI devices), I'll merge it right away.
Thanks,
