Jonathan McDowell 2ab2178c33 USB: Fix option_ms regression in 2.6.31-rc2
Commit 32ebbe7b6a which filters the
SCSI REZERO command in option_ms based on a SCSI INQUIRY with a vendor
of Option breaks my Option Icon 225 (0af0:6971). This device returns a
vendor of ZCOPTION for the ZeroCD device. The following trivial patch
fixes things for me.

Josua Dietze 32ebbe7b6a USB: usb-storage: add filter to "option_ms" to leave unrecognized devices alone
Some unusual usb devices from the maker "Option" are switched from
storage to serial/modem mode by sending a SCSI REZERO command. In one
case a fairly common vendor/device ID is affected which led to problems
for users of other modems or phones which are not supposed to be
switched.

The patch adds a filter by reading the vendor name with the SCSI INQUIRY
command, and skips the switching code for all unrecognized entries.

Further changes are cleanups and corrections pointed out by Alan Stern.

Tested with two devices with the IDs 05c6:1000, one from "Option" and
switchable, and one from Samsung (cell phone).

Alan Stern be475d9027 USB: usb-storage: fix return values from init functions
This patch (as1242) fixes the return values from the special
init functions in usb-storage.  They are supposed to return 0 for
success, not USB_STOR_TRANSPORT_GOOD.

Pascal Terjan c5be1b52d9 USB: Ignore storage device in modem mode on DWN-652
D-Link DWN-652 in Modem mode exposes 3 interfaces
- First one is the USB storage one
- Second one is for both control and connection
- Third one is unknown

This patch avoids usb-storage trying to switch again when already in
modem mode, and exposes only 2 ttyUSB instead of 3 by not attaching
to the storage interface

Dan Williams 281b064f23 USB: unusual dev for Option N.V. ZeroCD modems
Many newer Option mobile broadband devices initially provide a
usb-storage "driver CD" device that's pretty useless on Linux since
any software on it most likely wouldn't be compatible with your
kernel or distro anyway.  Thus, by default just kill the driver
CD device by sending the SCSI 'rezero' command, but allow override
of the default behavior via usb-storage module parameter so users
can keep the ZeroCD device if they really want to.  Inspired by
the Sierra TruInstall patch.
