Fixed bug #1080 Markus Rathgeb 2011-01-23 14:34:23 PST With kernel 2.6.31 the struct input_absinfo defined in linux/input.h changed. A field "__s32 resolution" was added at the end of the struct. Because the macro EVIOCGABS(abs) is using the struct input_absinfo, it would be better (IMHO) to change the declaration of variable values to "int values[sizeof(struct input_absinfo) / sizeof(int)];" or using "struct input_absinfo" directly.
