Bjørn Mork 726a09a78f USB: sierra: QMI mode MC7710 moved to qcserial
The MC7710 in QMI mode does not support the vendor
specific USB requests used by this driver.  The most
noticable effect of this is a 5 second delay as each
serial port is probed, caused by the set_power_state
command timing out:

 [   17.434291] usbcore: registered new interface driver sierra
 [   17.434383] USB Serial support registered for Sierra USB modem
 [   17.434486] sierra 8-4:1.0: Sierra USB modem converter detected

 [   27.432562] sierra 8-4:1.3: Sierra USB modem converter detected
 [   32.432463] usb 8-4: Sierra USB modem converter now attached to ttyUSB2

The MC7710 provide the same Qualcomm serial interfaces
as Gobi modules, and the qcserial driver has been extended
to support the module instead of this driver.

Bjørn Mork 1937131a01 USB: qcserial: adding Sierra Wireless devices
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

Bjørn Mork e7ad21e00e USB: qcserial: support generic Qualcomm serial ports
No need to verify the interface layout when doing
interface number based matching.  We can safely trust
the device ID table in this case.

This allows the driver to support any USB interface
layout for non-Gobi 1k/2k+ devices.

Alan Stern 0b84704a2d USB: serial-generic: use a single set of device IDs
The usb-serial-generic driver uses different device IDs for its USB
matching and its serial matching.  This can lead to problems: The
driver can end up getting bound to a USB interface without being
allowed to bind to the corresponding serial port.

This patch (as1557) fixes the problem by using the same device ID
table (the one that can be altered by the "vendor=" and "product="
module parameters) for both purposes.  The unused table is removed.
Now the driver will bind only to the intended devices.

Bjørn Mork 954c3f8a5f USB: serial: Enforce USB driver and USB serial driver match
We need to make sure that the USB serial driver we find
matches the USB driver whose probe we are currently
executing. Otherwise we will end up with USB serial
devices bound to the correct serial driver but wrong
USB driver.

An example of such cross-probing, where the usbserial_generic
USB driver has found the sierra serial driver:

So we end up with a mismatch between the USB driver and the
USB serial driver.  The reason for the above is simple: The
USB driver probe will succeed if *any* registered serial
driver matches, and will use that serial driver for all
serial driver functions.

This makes ref counting go wrong. We count the USB driver
as used, but not the USB serial driver.  This may result
in Oops'es as demonstrated by Johan Hovold <jhovold@gmail.com>:

Fix by only evaluating serial drivers pointing back to the
USB driver we are currently probing.  This still allows two
or more drivers to match the same device, running their
serial driver probes to sort out which one to use.

This reverts commit 6971113e10.

As Alan pointed out, this really isn't needed as it doesn't handle this
properly.  Ideally this should be handled by the usb-serial core one
day.  So revert it.

Greg Kroah-Hartman dcd82cd1c2 USB: serial: fix up reset_resume callback
If the usb-serial driver doesn't have a reset_resume callback, then we
need to tell the USB core that it doesn't, and it needs to rebind the
device.

Thanks to Alan for pointing out my mistake, and providing the fix.
