I would be amazed if the IRDA code still works. It's not been tested
properly for years and it never followed the tty rules properly in the
first place - so this looks good, although moving IRDA into staging
and /dev/null would IMHO be far better.

IRDA is dead, and IR remotes are handled via completely different code.
