These rules are broken, and match also on firewire devices and not only video4linux devices.
Such rules are not part of the standard udev setup and need to be fixed to work as intended. There is no change or fault at the kernel side. You may just disable the firefire drivers if you don't need them.
Btw, swapping default kernel names to devfs names and create symlinks for the kernel names is not recommended at all.
