There are binary sysfs attributes.

Aren't they to be used for things like ROMs and EEPROMs exclusively?

For ioctl you also need to open and
close the device.

Sure, but I do it once.

Plus, how often do you expect to perform this
operation? Don't you think you are trying to optimize something that
does not have any real performavnce impact here?

Maybe, anyway it will have to work before it's included in the kernel,
so I don't worry too much about it. Perhaps we should then merge the
lirc patches so both driver sets can be improved?
