The IRDA code has long been obsolete and broken.  So, to keep people
from trying to use it, and to prevent people from having to maintain it,
let's move it to drivers/staging/ so that we can delete it entirely from
the kernel in a few releases.

No objection, I'll apply this to net-next, thanks Greg.

IRDA works fine in Debian 9 (kernel 4.9) and I use it for simple file 
transfer. Hope I'm not the only one...

Odd, and is this just a ir device connected to a "real" serial port, or
a specific IRDA device?

thanks,
