Add support for the two interfaces provided by the Wacom DTI-520 tablet. This
allows both the tablet itself as well as the hardware buttons to be seen by the
kernel.

Hi all,
I'm resending this and CC'ing the linuxwacom-devel list as suggested. There
are no changes since the previous post. This is the kernel code that makes the
tablet appear as an input device.
Cheers,
Adam.

I don't have the device to test this patch. Just to share my comments
(inline) based on the code itself. I am cc'ing linux-input, where this
patch normally goes.

The line above should be after the if statement below. Otherwise
wacom->tool can be uninitialized.

Looks like we could define default vaules for those buttons.
