-HSO: add option hso driver
-
-This driver is for a number of different Option devices. Originally
-written by Option and Andrew Bird, but cleaned up massivly for
-acceptance into mainline by me and others.
-
-Many thanks to the following for their help in cleaning up the driver by
-providing feedback and patches to it:
- - Paulius Zaleckas <paulius.zaleckas@teltonika.lt>
- - Oliver Neukum <oliver@neukum.org>
- - Alan Cox <alan@lxorguk.ukuu.org.uk>
