Well, for IR *output* it doesn't make sense to disable evdev. One more
reason which indicates it probaably is better to introduce a ioctl to
disable evdev reporting. lircd will probably turn it off, especially
when sending data to uevent. debug tools might not, likewise apps
sending IR.

Such as throwing away the address part of rc5 codes ...

cheers,
