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.
