This patch removes IrPORT and the old dongle drivers (all off them
have replacement drivers).

- * This driver is ment to be a small half duplex serial driver to be
- * used for IR-chipsets that has a UART (16550) compatibility mode.
- * Eventually it will replace irtty, because of irtty has some
- * problems that is hard to get around when we don't have control
- * over the serial driver. This driver may also be used by FIR
- * drivers to handle SIR mode for them.

- * Belkin is selling a dongle called the SmartBeam.
- * In fact, there is two hardware version of this dongle, of course with
- * the same name and looking the exactly same (grrr...).
- * I guess that I've got the old one, because inside I don't have
- * a jumper for IrDA/ASK...
- *
- * As far as I can make it from info on their web site, the old dongle
- * support only 9600 b/s, which make our life much simpler as far as
- * the driver is concerned, but you might not like it very much ;-)
- * The new SmartBeam does 115 kb/s, and I've not tested it...
- *
- * Belkin claim that the correct driver for the old dongle (in Windows)
- * is the generic Parallax 9500a driver, but the Linux LiteLink driver
- * fails for me (probably because Linux-IrDA doesn't rate fallback),
- * so I created this really dumb driver...
- *
- * In fact, this driver doesn't do much. The only thing it does is to
- * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
- * driver is called "old_belkin" so that when the new SmartBeam is supported
- * its driver can be called "belkin" instead of "new_belkin".
- *
- * Note : this driver was written without any info/help from Belkin,
- * so a lot of info here might be totally wrong. Blame me ;-)
