USB: keyspan: fix NULL-pointer dereferences and memory leaks

2012-10-25T16:37:13+00:00

Fix NULL-pointer dereference at release by moving port data allocation
and deallocation to port_probe and port_remove.

Fix NULL-pointer dereference at disconnect by stopping port urbs at
port_remove.

Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer accessible at
disconnect or release.

Note that this patch also fixes port and interface-data memory leaks in
the error path of attach should port initialisation fail for any port.

Compile-only tested.

USB: serial: keyspan: remove dbg() usage

2012-09-14T23:30:23+00:00

dbg() was a very old USB-serial-specific macro.
This patch removes it from being used in the keyspan
driver and uses dev_dbg() instead.

USB: serial: rework usb_serial_register/deregister_drivers()

2012-05-08T22:46:14+00:00

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.

USB: serial: remove usb_serial_disconnect call in all drivers

2012-05-07T21:02:13+00:00

This is now set by the usb-serial core, no need for the driver to
individually set it.

Thanks to Alan Stern for the idea to get rid of it.

usb-serial: use new registration API in [k-m]* drivers

2012-02-24T20:39:19+00:00

This patch (as1526) modifies the following usb-serial drivers to
utilize the new usb_serial_{de}register_drivers() routines:

	keyspan, kl5kusb105, kobil_sct, mct_u232, mos7720,
	mos7840, and moto_modem.

tiocmset: kill the file pointer argument

tiocmget: kill off the passing of the struct file

2011-02-17T19:47:33+00:00

We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

USB serial: add missing .usb_driver field in serial drivers

2011-01-23T02:38:59+00:00

This patch (as1443) fixes a bug found in many of the USB serial
drivers: They don't set the .usb_driver field in their
usb_serial_driver structure.  This field is needed for assigning
dynamic IDs for device matching.

In addition, starting with the 2.6.37 kernel, the .usb_driver field is
needed for proper autosuspend operation.  Without it, attempts to open
the device file will fail.
