CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed.

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

serial: add a new helper function

2012-09-05T20:28:35Z

In most of the time, the driver needs to check if the cts flow control is enabled. But now, the driver checks the ASYNC_CTS_FLOW flag manually, which is not a grace way. So add a new wraper function to make the code tidy and clean. Signed-off-by: Huang Shijie Signed-off-by: Greg Kroah-Hartman

TTY: mxser, fix invalid module_parm permissions

2012-08-13T23:57:58Z

444 means 0674 and we do not definitely want that. Use S_IRUGO which is much more safer. Signed-off-by: Jiri Slaby Reported-by: Rusty Russell 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

mxser: allow overlapping vector

2012-08-10T20:29:57Z

For many cards, this saves some IO space because interrupt status port has precedence over the rest of ports on the card. Hence it can be mapped to a hole in I/O ports. Here we add a kernel parameter which allows that if a user wants to. But they need to explicitly enable it by a module parameter. Signed-off-by: Jiri Slaby 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: mxser: local variables should not be exposed globally

2012-05-04T23:42:14Z

The variable 'mxser_port_ops' is only referenced in this file and should be marked static to prevent it from being exposed globally. Quites the sparse warning: warning: symbol 'mxser_port_ops' was not declared. Should it be static? Signed-off-by: H Hartley Sweeten Cc: Jiri Slaby Acked-by: Alan Cox Signed-off-by: Greg Kroah-Hartman
