	replaced by the skge driver. 

Who:    Stephen Hemminger <shemminger@osdl.org>



---------------------------



What:	Compaq touchscreen device emulation

When:	Oct 2007

Files:	drivers/input/tsdev.c

Why:	The code says it was obsolete when it was written in 2001.

	tslib is a userspace library which does anything tsdev can do and

	much more besides in userspace where this code belongs. There is no

	longer any need for tsdev and applications should have converted to

	use tslib by now.

	The name "tsdev" is also extremely confusing and lots of people have

	it loaded when they don't need/use it.
