Linus,

Here are the new IrDA patches for Linux-2.4.0-test10. Please apply them to
your latest 2.4 code. If you decide to apply them, then I suggest you start
with the first one (irda1.diff) and work your way to the last one 
(irda24.diff) since most of them are not commutative. 

The name of this patch is irda15.diff. 

(Many thanks to Jean Tourrilhes for splitting up the big patch)

[FEATURE] : Add a new feature to the IrDA stack
[CORRECT] : Fix to have the correct/expected behaviour
[CRITICA] : Fix potential kernel crash
[OUPS   ] : Error that will be fixed in a later patch

irda15.diff :
-----------------
        o [-OUPS  ] Missing a bit for -> module init change
        o [CRITICA] IrLAN update (was broken - various things)
