tty: ioc4_serial.c: move assignment out of if () block

2015-05-10T17:04:17+00:00

We should not be doing assignments within an if () block
so fix up the code to not do this.

change was created using Coccinelle.

serial: ioc4_serial: Staticize ioc4_serial_attach_one()

2013-08-12T18:35:32+00:00

ioc4_serial_attach_one() is used only in this file.
Also, ioc4_serial is not used; it can be removed.
Fix the following sparse warnings:

drivers/tty/serial/ioc4_serial.c:300:3: warning: symbol 'ioc4_serial' was not declared. Should it be static?
drivers/tty/serial/ioc4_serial.c:2771:1: warning: symbol 'ioc4_serial_attach_one' was not declared. Should it be static?

TTY: switch tty_flip_buffer_push

2013-01-16T06:30:15+00:00

Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty in many
call sites. Only tty_port will needed and hence no more
tty_port_tty_get in those paths.

Now, the one where most of tty_port_tty_get gets removed:
tty_flip_buffer_push.

IOW we also closed all the races in drivers not using tty_port_tty_get
at all yet.

Also we move tty_flip_buffer_push declaration from include/linux/tty.h
to include/linux/tty_flip.h to all others while we are changing it
anyway.

TTY: move low_latency to tty_port

2013-01-16T06:23:16+00:00

One point is to have less places where we actually need tty pointer.
The other is that low_latency is bound to buffer processing and
buffers are now in tty_port. So it makes sense to move low_latency to
tty_port too.

call sites. Only tty_port will needed and hence no more
tty_port_tty_get in those paths.

tty_insert_flip_string this time.

TTY: switch tty_buffer_request_room to tty_port

Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty pointer in
many call sites. Only tty_port will be needed and hence no more
tty_port_tty_get calls in those paths.

Here we start with tty_buffer_request_room.

serial: avoid double free after call ioc4_serial_remove_one

2013-01-16T05:54:41+00:00

  before goto out5,  soft, control, serial are all assigned to idd
  after finish call ioc4_serial_remove_one, all resources are released
  we need return instead of go on, or double free

TTY: serial: move the dereference below the NULL test

2012-09-10T23:33:02+00:00

The dereference should be moved below the NULL test.

spatch with a semantic match is used to found this.

tty: move the termios object into the tty

2012-07-16T20:00:41+00:00

This will let us sort out a whole pile of tty related races. The
alternative would be to keep points and refcount the termios objects.
However
1. They are tiny anyway
2. Many devices don't use the stored copies
3. We can remove a pty special case
