[PATCH v3 0/4] Regression fixes for rfcomm/tty.c

The following patches fix three regressions introduced with the
rfcomm tty_port conversion.

The first patch restores the expected behaviour of the rfcomm port when
it's created with the flag RFCOMM_RELEASE_ONHUP.

The second patch moves rfcomm_get_device() and is preparatory for the
third patch.

The third patch fixes two regressions:
1) when the tty is opened with O_NONBLOCK or CLOCAL is set (fixes
   wvdial)
2) when the rfcomm device is created with the flag RFCOMM_REUSE_DLC
   (fixes ModemManager)

The fourth patch removes rfcomm_dev_carrier_raised().

Changes from v2:
  * Fix the style of if statements in rfcomm_dev_activate().

Changes from v1:
  * Removed the device_move() fix which is now incorporated in a new patch.

Gianluca Anzolin (4):
  rfcomm: release the port when the last user closes the tty
  rfcomm: move rfcomm_get_device() before rfcomm_dev_activate()
  rfcomm: always wait for a bt connection on open()
  rfcomm: remove rfcomm_carrier_raised()
