tty: rocket: Explicitly list supported PCI IDs

2013-01-18T01:28:39Z

Matching PCI_ANY_ID causes conflicts with RocketPort 2 adapters, which are supported by a different driver. Signed-off-by: Kevin Cernekee Signed-off-by: Greg Kroah-Hartman

tty: add parenthesis to macro POLL_PERIOD in rocket.c

2013-01-16T06:49:36Z

Macros should be enclosed in parenthesis Signed-off-by: Cong Ding Signed-off-by: Greg Kroah-Hartman

TTY: switch tty_flip_buffer_push

2013-01-16T06:30:15Z

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: switch tty_insert_flip_char

2013-01-16T06:21:36Z

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. tty_insert_flip_char is the next one to proceed. This one is used all over the code, so the patch is huge.

TTY: convert more flipping functions

2013-01-16T06:17:29Z

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. Now 4 string flipping ones are on turn: * tty_insert_flip_string_flags * tty_insert_flip_string_fixed_flag * tty_prepare_flip_string * tty_prepare_flip_string_flags Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

tty: remove use of __devinitdata

2012-11-21T23:25:06Z

CONFIG_HOTPLUG is going away as an option so __devinitdata is no longer needed. Signed-off-by: Bill Pemberton Cc: Alan Cox Cc: Peter Korsgaard Signed-off-by: Greg Kroah-Hartman

TTY: call tty_port_destroy in the rest of drivers

2012-11-16T01:20:58Z

After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places. Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

TTY: use tty_port_register_device

2012-08-13T23:50:19Z

Currently we have no way to assign tty->port while performing tty installation. There are two ways to provide the link tty_struct => tty_port. Either by calling tty_port_install from tty->ops->install or tty_port_register_device called instead of tty_register_device when the device is being set up after connected. In this patch we modify most of the drivers to do the latter. When the drivers use tty_register_device and we have tty_port already, we switch to tty_port_register_device. So we have the tty_struct => tty_port link for free for those. Signed-off-by: Jiri Slaby Acked-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

tty: move the termios object into the tty

2012-07-16T20:00:41Z

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 Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

TTY: remove unneeded tty->index checks

2012-03-08T19:42:21Z

Checking if tty->index is in bounds is not needed. The tty has the index set in the initial open. This is done in get_tty_driver. And it can be only in interval <0,driver->num). So remove the tests which check exactly this interval. Some are left untouched as they check against the current backing device count. (Leaving apart that the check is racy in most of the cases.)
