Hi Jeff, all,

don' t know excactly where to send this to.
I had a little spare time this week as my doctor grounded me, so to
relax I did a bit of kernel hacking and get my notebook working. 8-)

This patch adds the "alloc_irdadev" primitive to Linux-2.4 . Modeled
after and code stolen from Linux-2.6 .
This enables practically drop-in addition of Linux-2.6 IRDA drivers
to Linux-2.4.

This patch is prerequisite for another patch from me which adds
via-ircc to the IRDA driver modules.

Patch against linux-2.4.24-0pre2.1mdk from current Mandrake Cooker.
Should apply to vanilla Linux-2.4.24 as well.
