Simplify the patch compared to v1 as suggested by Bjørn Mork by taking advantage of the fact that existing devices work with sendsetup = true too. Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID 0x9090. Tests with several MC73xx/MC74xx/MC77xx devices have been performed in order to verify backward compatibility.

Simplify the patch compared to v1 as suggested by Bjørn Mork by taking advantage of the fact that existing devices work with sendsetup = true too. Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID 0x9090. Tests with several MC73xx/MC74xx/MC77xx devices have been performed in order to verify backward compatibility.

usb: usb_wwan: replace release and disconnect with a port_remove hook Doing port specific cleanup in the .port_remove hook is a lot simpler and safer than doing it in the USB driver .release or .disconnect methods. The removal of the port from the usb-serial bus will happen before the USB driver cleanup, so we must be careful about accessing port specific driver data from any USB driver functions. This problem surfaced after the commit 0998d0631 device-core: Ensure drvdata = NULL when no driver is bound which turned the previous unsafe access into a reliable NULL pointer dereference.

USB: serial: rework usb_serial_register/deregister_drivers() 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.
