The le32_to_cpu function doesn't quite work for some reason. Manually
writing the 32-bit conversion seems to fix the axes reporting for
ABS_X, ABS_Y and ABS_RZ.
This still could use a bit of investigation to see why
input_set_abs_params called with non-zero values for fuzz and flat
causes axis motion to be ignored, although it may be a driver
subsystem issue in Linux.
Due to plans to scrap the kernel module approach and go with a full-fledged
userspace application, this commit renames the driver folder to kernel_module
so the folder contents are clear.
