Thanks a lot for the follow-up Jiri.

If you guys decide to remove hid-thingm.c, you need to update the
MAINTAINERS entry, checkpatch.pl should have warned about that.

I can hardly test the patchset now. Heiner, can you confirm me that with
your patchset, we will still see 3 led_classdev in sysfs for the
blink(1) mk1 (which has one RGB chip) and 6 for mk2 (which has 2 chips)?

Thanks,

        Vivien
