We have a real Bluetooth system in Linux, lets finally delete this driver as no
one is using it (and if they are, they are using a closed source bluetooth
stack, which I can't support anyway.)

Marcel, you owe me a beer :)

- * USB Bluetooth TTY driver, based on the Bluetooth Spec version 1.0B
- * 
- * (2001/11/30) Version 0.13 gkh
- *     - added locking patch from Masoodur Rahman <rmasoodu@in.ibm.com>
- *     - removed active variable, as open_count will do.
- *
- * (2001/07/09) Version 0.12 gkh
- *     - removed in_interrupt() call, as it doesn't make sense to do 
- *       that anymore.
- *
- * (2001/06/05) Version 0.11 gkh
- *     - Fixed problem with read urb status saying that we have shutdown,
- *       and that we shouldn't resubmit the urb.  Patch from unknown.
- *
- * (2001/05/28) Version 0.10 gkh
- *     - Fixed problem with using data from userspace in the bluetooth_write
- *       function as found by the CHECKER project.
- *     - Added a buffer to the write_urb_pool which reduces the number of
- *       buffers being created and destroyed for ever write.  Also cleans
- *       up the logic a bit.
- *     - Added a buffer to the control_urb_pool which fixes a memory leak
- *       when the device is removed from the system.
- *
- * (2001/05/28) Version 0.9 gkh
- *     Fixed problem with bluetooth==NULL for bluetooth_read_bulk_callback
- *     which was found by both the CHECKER project and Mikko Rahkonen.
- *
- * (08/04/2001) gb
- *     Identify version on module load.
- *
- * (2001/03/10) Version 0.8 gkh
- *     Fixed problem with not unlinking interrupt urb on device close
- *     and resubmitting the read urb on error with bluetooth struct.
- *     Thanks to Narayan Mohanram <narayan@RovingNetworks.com> for the
- *     fixes.
- *
- * (11/29/2000) Version 0.7 gkh
- *     Fixed problem with overrunning the tty flip buffer.
- *     Removed unneeded NULL pointer initialization.
- *
- * (10/05/2000) Version 0.6 gkh
- *     Fixed bug with urb->dev not being set properly, now that the usb
- *     core needs it.
- *     Got a real major id number and name.
- *
- * (08/06/2000) Version 0.5 gkh
- *     Fixed problem of not resubmitting the bulk read urb if there is
- *     an error in the callback.  Ericsson devices seem to need this.
- *
- * (07/11/2000) Version 0.4 gkh
- *     Fixed bug in disconnect for when we call tty_hangup
- *     Fixed bug in bluetooth_ctrl_msg where the bluetooth struct was not
- *     getting attached to the control urb properly.
- *     Fixed bug in bluetooth_write where we pay attention to the result
- *     of bluetooth_ctrl_msg.
- *
- * (08/03/2000) Version 0.3 gkh mdc
- *     Merged in Mark's changes to make the driver play nice with the Axis
- *     stack.
- *     Made the write bulk use an urb pool to enable larger transfers with
- *     fewer calls to the driver.
- *     Fixed off by one bug in acl pkt receive
- *     Made packet counters specific to each bluetooth device 
- *     Added checks for zero length callbacks
- *     Added buffers for int and bulk packets.  Had to do this otherwise 
- *     packet types could intermingle.
- *     Made a control urb pool for the control messages.
- *
- * (07/11/2000) Version 0.2 gkh
- *     Fixed a small bug found by Nils Faerber in the usb_bluetooth_probe 
- *     function.
- *
- * (07/09/2000) Version 0.1 gkh
- *     Initial release. Has support for sending ACL data (which is really just
- *     a HCI frame.) Raw HCI commands and HCI events are not supported.
- *     A ioctl will probably be needed for the HCI commands and events in the
- *     future. All isoch endpoints are ignored at this time also.
- *     This driver should work for all currently shipping USB Bluetooth 
- *     devices at this time :)
