USB: remove staging quatech_usb2 driver

2012-05-10T21:09:16Z

Now that we have a "real" driver for the quatech devices, we can remove the drivers/staging/quatech_usb2/ driver as it is no longer needed. Thanks to Bill Pemberton for writing the new driver. Cc: Richard Ash Cc: Bill Pemberton Signed-off-by: Greg Kroah-Hartman

USB: serial: rework usb_serial_register/deregister_drivers()

2012-05-08T22:46:14Z

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

2012-05-07T21:02:13Z

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: quatech_usb2.c: remove dbg() tracing calls

2012-05-04T23:17:49Z

dbg() was used a lot a long time ago to trace code flow. Now that we have ftrace, this isn't needed at all, so remove these calls. CC: Rusty Russell CC: Alan Stern CC: Mauro Carvalho Chehab CC: Kautuk Consul Signed-off-by: Greg Kroah-Hartman

USB: Staging: quatech_usb3: remove err() usage

2012-04-24T16:08:22Z

err() was a very old USB-specific macro that I thought had gone away. This patch removes it from being used in the driver and uses dev_err() instead Cc: Rusty Russell Cc: Alan Stern Cc: Mauro Carvalho Chehab Cc: Kautuk Consul Signed-off-by: Greg Kroah-Hartman

USB: serial: quatech_usb2.c: use module_usb_serial_driver

2012-02-28T21:11:27Z

This converts the quatech_usb2.c driver to use the module_usb_serial_driver() call instead of having to have a module_init/module_exit function, saving a lot of duplicated code. CC: Lucas De Marchi CC: Rusty Russell CC: Alan Stern CC: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

usb-serial: use new registration API in staging drivers

2012-02-24T20:39:22Z

This patch (as1530) modifies the following usb-serial drivers from drivers/staging to utilize the new usb_serial_{de}register_drivers() routines: quatech_usb2 and serqt_usb2. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20Z

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab Signed-off-by: Rusty Russell

staging: quatech_usb2: Potential lost wakeup scenario in TIOCMIWAIT

2011-09-19T17:46:18Z

If the usermode app does an ioctl over this serial device by using TIOCMIWAIT, then the code will wait by setting the current task state to TASK_INTERRUPTIBLE and then calling schedule(). This will be woken up by the qt2_process_modem_status on URB completion when the port_extra->shadowMSR is set to the new modem status. However, this could result in a lost wakeup scenario due to a race in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion for new modem status in qt2_process_modem_status. Due to this, the usermode app's task will continue to sleep despite a change in the modem status. Signed-off-by: Kautuk Consul Cc: stable Signed-off-by: Greg Kroah-Hartman
