Bluetooth rfcomm tty layer initialization

Bluetooth rfcomm tty layer initialization

[Jan Dittmer]

This was in 2.5 for a while. Happens when loading the rfcomm module.
Anything more needed for this? All bluetooth stuff is modular, and I'm 
using devfs.
I cannot capture the start of the rfcomm loading, the messages are 
scrolling far too fast and I don't have a serial console handy right 
now, sorry.

Thanks,

Jan

Yep. I'm aware of that problem. It's on my TOFIX list :)
