[PATCH] hid: egalax: Extend support for touchscreen used in "Samsung NB30 touch" netbook.

[Richard Nauber <richard.nauber@googlemail.com>]

Hi there,
I got me a brand new "Samsung NB30 touch" and with this patch I have 
the full multitouch power at my fingertips. At least at two of them... 

The patch applies to the 
git://git.kernel.org/pub/scm/linux/kernel/git/rydberg/input-mt.git 
tree at a528f7.

Have Fun.

BTW: I have not found a suitable tuio bridge for linux mt devices, 
so I wrote a small mtdev2tuio tool. It uses libmtdev and liblo 
and allows to interact with lots of existing software (e.g. a 
compiz plugin, numtyphysics, ...). If someone is interested, I 
can upload it (might take a while).
