* USB: qcserial: Fix support for HP lt4112 LTE/HSPA+ Gobi 4G ModemBjørn Mork2015-11-161-20/+34
| | | | | | | | | | | | | | | | | | | | The DEVICE_HWI type was added under the faulty assumption that Huawei devices based on Qualcomm chipsets and firmware use the static USB interface numbering known from Gobi devices. But this model does not apply to Huawei devices like the HP branded lt4112 (Huawei me906e). Huawei firmwares will dynamically assign interface numbers. Functions are renumbered when the firmware is reconfigured. Fix by changing the DEVICE_HWI type to use a simplified version of Huawei's subclass + protocol scheme: Blacklisting known network interface combinations and assuming the rest are serial.

* USB: qcserial: make AT URCs work for Sierra Wireless devicesDavid Ward2015-10-091-0/+11
| | | | | | | | | | | | | | | | | Three Sierra Wireless modems have been found to require the CDC ACM SET_CONTROL_LINE_STATE request on the AT port in order to receive unsolicited response codes, most recently the Dell Wireless 5808e (which is a re-branded Sierra Wireless EM7355). On the other hand, the Sierra Wireless MC7710 does not seem to need this request, but it was found to work either way. Use this request on the AT port of devices with the Sierra Wireless layout in the qcserial driver. The other modems that were moved to the option driver to work around this can now be moved back.

| | | | | | | | | | | | | | | | | | | | Fix port-data memory leak in usb-serial probe error path by moving port data allocation to port_probe. Since commit a1028f0abf ("usb: usb_wwan: replace release and disconnect with a port_remove hook") port data is deallocated in port_remove. This leaves a possibility for memory leaks if usb-serial probe fails after attach but before the port in question has been successfully registered. Note that this patch also fixes two additional memory leaks in the error path of attach should port initialisation fail for any port as the urbs were never freed and neither was the data of any of the successfully initialised ports.

* USB: qcserial: fix port handling on Gobi 1K and 2K+Dan Williams2012-08-161-18/+24
| | | | | | | | | | | | | | | Bjorn's latest patchset does break Gobi 1K and 2K because on both devices as it claims usb interface 0. That's because usbif 0 is not handled in the switch statement, and thus the if0 gets claimed when it should not. So let's just make things even simpler yet, and handle both the 1K and 2K+ cases separately. This patch should not affect the new Sierra device support, because those devices are matched via interface-specific matching and thus should never hit the composite code.

* usb: usb_wwan: replace release and disconnect with a port_remove hookBjørn Mork2012-08-101-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QMI mode of the Sierra Wireless MC7710 is close to a Gobi device, and also identified as one by the Windows drivers provided by Sony. The serial interfaces are the same as for any other Gobi module, but the USB interface layout is different: 0: DM/DIAG (also present in bootloader mode) 2: NMEA 3: AT-capable modem port 8: QMI/net 19: QMI/net (not always present) 20: QMI/net (not always present) Note in particular that the NMEA and AT ports are reversed compared to a Gobi 2k+ device, and that the DM port appears as a QDL port in bootloader mode using the same device ID. The Sony driver also document two new devices with standard Gobi 2k+ layout (1199:68a5, 1199:68a9) having a QDL mode (1199:68a4, 1199:68a8). Adding these as well. Lenovo Windows drivers document the USB interface layout for a few additional Sierra Wireless devices. Adding these while at it: - MC7770 (1199:901b) with standard Gobi 2k+ layout - MC7700 (0f3d:68a2) with the same layout as MC7710 - MC7750 (114f:68a2) with the same layout as MC7710 - EM7700 (1199:901c) with the same layout as MC7710 Cc: Anton Samokhvalov <pg83@yandex.ru> Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The same is true of the one remaining no_dynamic_id entry. reset_resume remains a small problem, because the serial core doesn't support it. The patch ignores these entries.
