tty: drop put_tty_driver

2021-07-27T10:17:21+00:00

put_tty_driver() is an alias for tty_driver_kref_put(). There is no need for two exported identical functions, therefore switch all users of old put_tty_driver() to new tty_driver_kref_put() and remove the former for good.

ttyprintk: remove redundant initialization of variable i

2021-05-27T12:19:50+00:00

The variable i is being initialized with a value that is never read, it is being updated later on. The assignment is redundant and can be removed.

ttyprintk: Removed unnecessary TTY ioctl callback

2021-05-13T16:29:12+00:00

It turns-out, that TIOCCONS is completely handled in tty_io.c, so the current local ioctl callback is of no real use. Signed-off-by: Samo Pogačnik Link: https://lore.kernel.org/r/1502946c760b1aae3ad9cffcf4ea3b9f37206585.camel@t-2.net Signed-off-by: Greg Kroah-Hartman

ttyprintk: Add TTY port shutdown callback

2021-05-13T16:29:12+00:00

By adding the TTY port shutdown callback, the final buffer flush has been moved from tpk_close() to tpk_port_shutdown(). This enables buffer flush upon close and hangup as well. The change also removes the specific 'buf == NULL' handling in tpk_printk(), which became useless.

tty: make tty_operations::write_room return uint

2021-05-13T15:03:20+00:00

Line disciplines expect a positive value or zero returned from tty->ops->write_room (invoked by tty_write_room). So make this assumption explicit by using unsigned int as a return value. Both of tty->ops->write_room and tty_write_room.
