commit 633ba7876b96ec339ef685357e2f7c60b5a8ce85 broke
g_file_storage functionality by enabling AUTOCLEAR on
all cases without caring for all gadget drivers.

This patch will only enable AUTOCLEAR if our endpoint's
FIFO was configured with double buffering support. Note
this is not a complete fix, double buffered case still
doesn't work always, but that hasn't been working for
quite some time. Other than reverting the entire commit
and breaking testusb with double buffered case again,
I decided it was better to fix the single buffered case
and spend more time fixing double buffered case properly.

Enabling CONFIG_USB_MUSB_DEBUG option causes -DDEBUG to be added to gcc's
command line, however the DBG() macro doesn't depend on DEBUG, so that the
debugging messages get printed regardless of the option, and I don't think
that this was intended. Get rid of otherwise unused xprintk() macro and make
DBG() macro directly call pr_debug() which only results in the actual code
generated if DEBUG is defined.

This change makes musb_hdrc.o ~30% less in size with CONFIG_USB_MUSB_DEBUG

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:
	https://www.codeaurora.org/patches/quic/gobi/
  Enable/disable GPS via:
        echo "\$GPS_START" > /dev/ttyUSB2
        # use GPS
        echo "\$GPS_STOP"  > /dev/ttyUSB2

This reverts commit 6a1a82df.

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

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.

This patch, adds to the option driver the Onda Communication

device id.

Note that many variants of this same device are being release here in
Italy (at least one or two per telephony operator).

These devices are perfectly equivalent except for some predefined
settings (which can be changed of course).

It should be noted that most ONDA devices are allready supported (they
used other vendor's ids in the past). The patch seems working fine here,
and the rest of the driver seems uninfluenced.

There are lots of ZTE USB id's currently not covered by usb/serial. Adds them,
to allow those devices to work properly on Linux.

While here, put the USB ID's for 0x2002/0x2003 at the sorted order.

This patch is based on zte.c file found on MF645.

PS.: The ZTE driver is commenting the USB ID for 0x0053. It also adds, commented,
an USB ID for 0x0026.

Not sure why, but I think that 0053 is used by their devices in storage mode only.
So, I opted to keep the comment on this patch.

drivers/usb/host/isp1362-hcd.c:1680: error: ‘ohci’ undeclared (first use in this function)

The problem is when the CONFIG_USB_OTG option is enabled.

ohci variable is never declared and there isn't any CONFIG_USB_OTG dependent code
besides the portion defined in isp1362_hub_control.

So I think that maybe USB OTG support is not needed/supported.

This patch removes the CONFIG_USB_OTG dependent block so the driver can compile cleanly.

Failing test case: From host do the following. I used libusb-1.0

1) Set configuration to zero.

		0, /* standard OUT */
		0x9, /* setConfiguration */
		0, 0, NULL, 0, 0);

2) Query current configuratioan.
	libusb_control_transfer(device_handle,
		0x80, /* standard IN*/
		0x8, /* getConfiguration */
		0, 0, data, 1, 0);

3) Send the non-standard ctrl transfer targetted to interface
	libusb_control_transfer(device_handle,
		0x81, /* standard IN to interface*/
		0x6, /* getDescriptor */
		0x2300, 0, data, 0x12, 0);

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.
