* USB: kobil_sct: use port interrupt-out urbJohan Hovold2013-04-17
| | | | | | | | | | | Use the port interrupt-out urb rather than abusing the port write_urb pointer and allocating a new urb at every open (but the first...). Note that the write_urb abuse would have led to a double free should there ever be interfaces with a bulk-out endpoint.

* TTY: switch tty_flip_buffer_pushJiri Slaby2013-01-15
| | | | | | | | | | | | | | | | | | | | 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.

* USB: serial: remove driver version informationJohan Hovold2012-10-31
| | | | | | | | | | | Remove all MODULE_VERSION macros and driver-version information (except for garmin_gps which uses it in a status reply).

* USB: kobil_sct: fix port-data memory leakJohan Hovold2012-10-17
| | | | | | | | | | | | | | | Fix port-data memory leak by replacing attach and release with port_probe and port_remove. Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no driver is bound) the port private data is no longer freed at release as it is no longer accessible. Compile-only tested.

There are also the usual XHCI set of updates, and other various driver changes and updates.

* USB: serial: rework usb_serial_register/deregister_drivers()Greg Kroah-Hartman2012-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reworks the usb_serial_register_drivers() and usb_serial_deregister_drivers() to not need a pointer to a struct usb_driver anymore. The usb_driver structure is now created dynamically and registered and unregistered as needed. This saves lines of code in each usb-serial driver. All in-kernel users of these functions were also fixed up at this time. The pl2303 driver was tested that everything worked properly. Thanks for the idea to do this from Alan Stern.

The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

* USB: removal of tty->low_latency hack dating back to the old serial codeOliver Neukum2009-04-23
| | | | | | | | | | | | This removes tty->low_latency from all USB serial drivers that push data into the tty layer at hard interrupt context. It's no longer needed and actually harmful.

* USB: remove info() macro from usb/serial driversGreg Kroah-Hartman2008-10-17
| | | | | | | USB should not be having it's own printk macros, so remove info() and use the system-wide standard of dev_info() wherever possible. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* tty: usb-serial krefsAlan Cox2008-10-13
| | | | | | | | | | | | | Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky. This also gives us a framework for general tty drivers to use tty_port objects and refcount. Contains two err->dev_err changes merged together to fix clashes in the -next tree.

* usb_serial: API all changeAlan Cox2008-07-22
| | | | | | | | | | | | | | | | | | | USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* USB serial: add driver pointer to all usb-serial driversJohannes Hölzl2007-02-07
| | | | | | | | | | | | | | Every usb serial driver should have a pointer to the corresponding usb driver. So the usb serial core can add a new id not only to the usb serial driver, but also to the usb driver. Also the usb drivers of ark3116, mos7720 and mos7840 missed the flag no_dynamic_id=1. This is added now. Signed-off-by: Johannes Hölzl <johannes.hoelzl@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
