If you read back in this thread you'll see how there was a discussion
already on how you shouldn't re-use major/minor numbers for other
purposes .. It looks like "hvc" was essentially overridden , which now
seems like a no-no given that discussion.. This appears to be a
sensitive topic.

It can't hurt anything to make this hvc driver a little more flexible in
this regard ..
