Input: tsdev - schedule removal 

Compaq touchscreen emulation (drivers/input/tsdev.c) is old,
was obsolete when it was written by the authors own admission
and much better userspace solutions like tslib now exist.
The name is also confusing.

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.
