      Bluetooth: don't release the port in rfcomm_dev_state_change() · 29cd718b
      Gianluca Anzolin authored
      When the dlc is closed, rfcomm_dev_state_change() tries to release the
      port in the case it cannot get a reference to the tty. However this is
      racy and not even needed.
      
      Infact as Peter Hurley points out:
      
      1. Only consider dlcs that are 'stolen' from a connected socket, ie.
         reused. Allocated dlcs cannot have been closed prior to port
         activate and so for these dlcs a tty reference will always be avail
         in rfcomm_dev_state_change() -- except for the conditions covered by
         #2b below.
      2. If a tty was at some point previously created for this rfcomm, then
         either
         (a) the tty reference is still avail, so rfcomm_dev_state_change()
             will perform a hangup. So nothing to do, or,
         (b) the tty reference is no longer avail, and the tty_port will be
             destroyed by the last tty_port_put() in rfcomm_tty_cleanup.
             Again, no action required.
      3. Prior to obtaining the dlc lock in rfcomm_dev_add(),
         rfcomm_dev_state_change() will not 'see' a rfcomm_dev so nothing to
         do here.
      4. After releasing the dlc lock in rfcomm_dev_add(),
         rfcomm_dev_state_change() will 'see' an incomplete rfcomm_dev if a
         tty reference could not be obtained. Again, the best thing to do here
         is nothing. Any future attempted open() will block on
         rfcomm_dev_carrier_raised(). The unconnected device will exist until
         released by ioctl(RFCOMMRELEASEDEV).
      
      The patch removes the aforementioned code and uses the
      tty_port_tty_hangup() helper to hangup the tty.
