* In old kernels (e.g: 2.6.18) sysfs file names must be shorter
then KOBJ_NAME_LEN.
* Longer names are truncated and this leads to duplicate names
which fails device_register()
Examples: "dahdi!channels!10!10" is truncated to "dahdi!channels!10!1"
* The fix shorten the names and make them fixed length. Example:
"dahdi!chan!010!010"
* It seems no current userspace tools rely on that name or on
/dev/dahdi/channels .
