hi
here my merge of the USB touchscreen drivers, based on my patch from
thursday for touchkitusb. this time it's a new driver...
and of course it's untested. i can test the egalax part next week...
[ also cc'ing the authors of the other drivers ]
the sizes for comparison:
text data bss dec hex filename
2942 724 4 3670 e56 touchkitusb.ko
2647 660 0 3307 ceb mtouchusb.ko
2448 628 0 3076 c04 itmtouch.ko
4097 1012 4 5113 13f9 usbtouchscreen.ko
comments?
