I tried to build channel on FreeBSD and got this error:

I hadn't though about supporting freebsd so far.
7844f81a45 should be an improvement but I still include a linux header.
not sure if freebsd has some sort of shim for this or how this works exactly.

it seems that freebsd does have evdev headers :D
it might actually work now

it built successfully now, thanks a lot, that was really fast. you can add freebsd to supported platform now, i guess :)
