* USB: visor: Match I330 phone more preciselyJason A. Donenfeld2015-04-29
| | | | | | | | | | | | | | | | | | | | | | | Samsung has just released a portable USB3 SSD, coming in a very small and nice form factor. It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.

| | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* USB: visor: always disable uart on closeJohan Hovold2013-03-25
| | | | | | | | | | | | Always try to disable the uart on close. Since the switch to tty ports, close will be called as part of shutdown before disconnect returns. Hence there is no need to check the disconnected flag, and we can put devices in disabled states also on driver unbind.

* 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.

At least Galaxy Spica is affected. This modem needs ACM driver and does not work with visor driver which binds the conflicting ID for SGH-I500.

* 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.

* USB: serial: fix regression in Visor/Palm OS module for kernels >= 2.6.24Brad Sawatzky2008-04-02
| | | | | | | | | | | | | | | | | | | | | | Fixes a bug/inconsistency revealed by the additional sanity checking in commit 063a2da8f01806906f7d7b1a1424b9afddebc443 introduced in the original 2.6.24 branch. The Handspring Visor / PalmOS 4 device structure defines .num_bulk_out=2 but the usb-serial probe returns num_bulk_out=3, triggering the check in the above commit and forcing a bail out when the device (a Garmin iQue in my case) attempts to connect. The patch bumps the expected number of endpoints to 3.
