There is nothing really to fix in udev, it knows nothing about ISDN.
The kernel defines the device node names these day, and udev manages
only permissions and possible symlinks.

devices.txt is just wrong in some things, and the common userspace
usage pattern is much closer to be a 'standard' here than this file.
devices.txt should catch up here. The same is true for scdX vs. srX,
scdX nodes don't exist today, and srX is not at all deprecated, unlike
devices.txt states.

The kernel provided ISDN nodes never made sense for applications using
ISDN. Also the devices.txt node names, I've never seen anywhere else
than in devices.txt.

The patch looks sane to me.
