Hm, this patch changes the LIRC interface but I can't see the according  
patch to the documentation.

Huh?

If you really want this new ioctl, then it should be clarified how it  
behaves in relation to LIRC_SET_MEASURE_CARRIER_MODE.

Do you have to enable the wide-band receiver explicitly before you can  
enable carrier reports or does enabling carrier reports implicitly switch  
to the wide-band receiver?

What happens if carrier mode is enabled and you explicitly turn off the  
wide-band receiver?

And while we're at interface stuff:
Do we really need LIRC_SETUP_START and LIRC_SETUP_END? It is only used  
once in lircd during startup.
