[BK] Add module refcounting for TTY line disciplines.

[Max Krasnyansky]

Linus,

This changeset adds module refcounting for TTY line disciplines. I've sent the patch to LKM earlier.
No negative comments (actually most people didn't seem to care). This is needed at least for 
Bluetooth and IrDA (Jean is ok with the patch).

Please pull from 
        bk://linux-bt.bkbits.net/ttymodref-2.5

This will update the following files:

 drivers/char/tty_io.c     |   16 ++++++++++++++++
 include/linux/tty_ldisc.h |    3 +++
 2 files changed, 19 insertions(+)

   [TTY] Add module reference counting for TTY line disciplines.
 

Thanks

Max
