	Hi Marcelo,

	Alan did fix the compile of the irtty driver for i386 in
pre8. Unfortunately, there is still many platforms which doesn't
compile, including some that I know where IrDA is heavily used (PPC,
	This patch make sure the code works on all platforms. It's
2.4.X, so I guess the code *must* work.



P.S. : Russel : this is an opportunity to fix the ARM platform
difference in the proper way. I guess irtty is still used on some ARM
platforms (especially with serial dongles).
