2.4.19: drivers/usb/wacom.c: Intuos tablet broken

Hello,

my apologies if that's old news, but I had reported the effect that my Intuos GD-1212 that worked with SuSE-8.0 (2.4.18) no longer worked with SuSE-8.1 (2.4.19). The bug was knows at SuSE as #22403, but they were unable to provide a solution so far.

Thus I did a diff to the kernel sources. It seems that the change in drivers/usb/wacom.c from RCS revision .122 to 1.23 (made by [email protected]) broke detection of move events in an obvious way (see lines 241 in 2.4.18 and lines 285 in 2.4.19):

wacom->x and wacom->y are no longer set in 2.4.19!

I'll attach my suggested fix (not tested).

Regards,
Ulrich Windl
P.S. I failed to get any programming info from Wacom, even if the documentation provided with the tablet said Wacom would support developers. If anybody here knows a source of information, please tell me...
