2012-10-31USB: serial: remove driver version informationJohan Hovold
Remove all MODULE_VERSION macros and driver-version information (except for garmin_gps which uses it in a status reply). It is the kernel version that matters and not some private version scheme which rarely even gets updated.

2012-10-25USB: digi_acceleport: fix port-data memory leakJohan Hovold
Fix port-data memory leak by moving port data allocation and deallocation to 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. Note that the oob port is never registered as a port device and should thus be handled in attach and release. Compile-only tested.

2012-10-01Merge tag 'usb-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usbLinus Torvalds
Pull USB changes from Greg Kroah-Hartman: "Here is the big USB pull request for 3.7-rc1 There are lots of gadget driver changes (including copying a bunch of files into the drivers/staging/ccg/ directory so that the other gadget drivers can be fixed up properly without breaking that driver), and we remove the old obsolete ub.c driver from the tree. There are also the usual XHCI set of updates, and other various driver changes and updates. We also are trying hard to remove the old dbg() macro, but the final bits of that removal will be coming in through the networking tree before we can delete it for good. All of these patches have been in the linux-next tree.

2012-05-08USB: serial: rework usb_serial_register/deregister_drivers()Greg Kroah-Hartman
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.

Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.

2008-07-22usb_serial: API all changeAlan Cox
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.

2007-02-07USB serial: add driver pointer to all usb-serial driversJohannes Hölzl
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.
