devices.txt is just bogus in this case and states stuff which was
never used in the real world. But you don't need to touch it. Just add
the naming hints (char *(*devnode)) to the capi class and nothing will
change, the device names in /sys and everywhere else will stay as they
are today, just devtmpfs and udev will create the right device nodes
out of the kernel supplied additional information. We did this for the
rest of the kernel the same way.
