Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ *
+ * 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 :)
