usb-storage: add new no_read_disc_info quirk
Appotech ax3003 (the larger brother of the ax203) based devices are even
more buggy then the ax203. They will go of into lala land when ever they
see a READ_DISC_INFO scsi command. So add a new US_FL which tells the
scsi sr driver to not issue any READ_DISC_INFO scsi commands.

scsi/sr: add no_read_disc_info scsi_device flag
Some USB devices emulate a usb-mass-storage attached (scsi) cdrom device,
usually this fake cdrom contains the windows software for the device.
While working on supporting Appotech ax3003 based photoframes, which do
this I discovered that they will go of into lala land when ever they see a
READ_DISC_INFO scsi command.
Thus this patch adds a scsi_device flag (which can then be set by the
usb-storage driver through an unsual-devs entry), to indicate this, and
makes the sr driver honor this flag.
I know this sucks, but as discussed on linux-scsi list there is no other
way to make this device work properly.
Looking at usb traces made under windows, windows never sends a
READ_DISC_INFO during normal interactions with a usb cdrom device. So as
this cdrom emulation thingie becomes more common we might see more of this
problem.

usb: gadget: goku_udc: Fix error path
This is based on an initial patch by Rahul Ruikar.
The goku_remove() function can be called before device_register() so it
can call device_unregister() improperly. Also if the call to
device_register() fails we need to call put_device().
As I was changing the error handling in goku_probe(), I noticed that
the label was "done" but actually if the function succeeds we return
earlier. I renamed the error path to "err" instead of "done."

USB: disable endpoints after unbinding interfaces, not before
This patch (as1430) fixes a bug in usbcore. When a device
configuration change occurs or a device is removed, the endpoints for
the old config should be completely disabled. However it turns out
they aren't; this is because usb_unbind_interface() calls
usb_enable_interface() or usb_set_interface() to put interfaces back
in altsetting 0, which re-enables the interfaces' endpoints.
As a result, when a device goes through a config change or is
unconfigured, the ep_in[] and ep_out[] arrays may be left holding old
pointers to usb_host_endpoint structures. If the device is
deauthorized these structures get freed, and the stale pointers cause
errors when the the device is eventually unplugged.
The solution is to disable the endpoints after unbinding the
interfaces instead of before. This isn't as large a change as it
sounds, since usb_unbind_interface() disables all the interface's
endpoints anyway before calling the driver's disconnect routine,
unless the driver claims to support "soft" unbind.
This fixes Bugzilla #19192. Thanks to "Tom" Lei Ming for diagnosing
the underlying cause of the problem.

Since commit
461972d8a4c94bc44f11a13046041c78a7cf18dd (musb_core: don't call
musb_platform_exit() twice), unloading the driver module results in a WARNING
"kobject: '(null)' (
c73de788): is not initialized, yet kobject_put() is being
called." (or even kernel oops) on e.g. DaVincis, though only in the OTG mode.
There exists dubious and unbalanced put_device() call in musb_free() which
takes place only in the OTG mode. As this commit caused musb_platform_exit()
to be called (and so unregister the NOP transceiver) before this put_device()
call, this function references already freed memory.
On the other hand, all the glue layers miss the otg_put_transceiver() call,
complementary to the otg_get_transceiver() call that they do. So, I think
the solution is to get rid of the strange put_device() call, and instead
call otg_put_transceiver() in the glue layers...

USB: qcserial: Enable Diagnostics Monitor and GPS ports on Gobi 2000
this patch to qcserial.c enables the Diagnostics Monitor
and NMEA GPS ports on Qualcomm Gobi 2000 devices.
A Gobi 2000 device will provide 3 serial ports:
# /dev/ttyUSB0 -> Diagnostics
# /dev/ttyUSB1 -> 3G Modem
# /dev/ttyUSB2 -> NMEA GPS port
* The Diagnostics Monitor uses Qualcomm's DM protocol; I used
libqcdm (ModemManager) to talk to it, found it working, but at
least DM commands 12 and 64 are not implemented on my device
(Gobi 2000 built into Thinkpad x100e).
* Functionality of the 3G Modem port remains unchanged.
* The GPS port and how to enable it has been confirmed now in the
Gobi 3000 source code at:

RTS and DTR should not be modified based on CRTSCTS when calling

Modem control lines are raised at port open by the tty layer and should stay
raised regardless of whether hardware flow control is enabled or not.
This is in conformance with the way serial ports work today and many
applications depend on this behaviour to be able to talk to hardware
implementing hardware flow control (without the applications actually using
it).
Hardware which expects different behaviour on these lines can always
use TIOCMSET/TIOCMBI[SC] after port open to change them.

OHCI: work around for nVidia shutdown problem
This patch (as1417) fixes a problem affecting some (or all) nVidia
chipsets. When the computer is shut down, the OHCI controllers
continue to power the USB buses and evidently they drive a Reset
signal out all their ports. This prevents attached devices from going
to low power. Mouse LEDs stay on, for example, which is disconcerting
for users and a drain on laptop batteries.
The fix involves leaving each OHCI controller in the OPERATIONAL state
during system shutdown rather than putting it in the RESET state.
Although this nominally means the controller is running, in fact it's
not doing very much since all the schedules are all disabled. However
there is ongoing DMA to the Host Controller Communications Area, so
the patch also disables the bus-master capability of all PCI USB
controllers after the shutdown routine runs.
The fix is applied only to nVidia-based PCI OHCI controllers, so it
shouldn't cause problems on systems using other hardware. As an added
safety measure, in case the kernel encounters one of these running
controllers during boot, the patch changes quirk_usb_handoff_ohci()
(which runs early on during PCI discovery) to reset the controller
before anything bad can happen.

usb gadget: don't save bind callback in struct usb_composite_driver
The bind function is most of the time only called at init time so there
is no need to save a pointer to it in the composite driver structure.
This fixes many section mismatches reported by modpost.

usb gadget: don't save bind callback in struct usb_gadget_driver
To accomplish this the function to register a gadget driver takes the bind
function as a second argument. To make things clearer rename the function
to resemble platform_driver_probe.
This fixes many section mismatches like
WARNING: drivers/usb/gadget/g_printer.o(.data+0xc): Section mismatch in
reference from the variable printer_driver to the function
.init.text:printer_bind()
The variable printer_driver references
the function __init printer_bind()
All callers are fixed.

USB: gadget: composite: Better string override handling
The iManufatcurer, iProduct and iSerialNumber composite module
parameters were only used when the gadget driver registers
strings for manufacturer, product and serial number. If the
gadget never bothered to set corresponding fields in USB device
descriptors those module parameters are ignored.
This commit makes the parameters work even if the strings ID
have not been assigned. It also changes the way IDs are
overridden -- what IDs are overridden is now saved in
usb_composite_dev structure -- which makes it unnecessary to
modify the string tables the way previous code did.
The commit also adds a iProduct and iManufatcurer fields to the
usb_composite_device structure. If they are set, appropriate
strings are reserved and added to device descriptor. This makes
it unnecessary for gadget drivers to maintain code for setting
those. If iProduct is not set it defaults to
usb_composite_device::name; if iManufatcurer is not set
a default "<system> <release> with <gadget-name>" is used.
The last thing is that if needs_serial field of
usb_composite_device is set and user failed to provided
iSerialNumber parameter a warning is issued.
