This patch (as883) removes an out-of-date WARN_ON from the main HCD
endpoint-disable routine. The warning is triggered whenever an
endpoint is disabled while the root hub is suspended. In the past
that may not have been legal, but it definitely is legal now. Merely
unbinding a USB driver will do it.
Furthermore, I've never seen any occurrences of this warning that
really did signal an actual bug or error condition. At this point it
has outlived its purpose.

This patch (as879) ties up some loose ends from an earlier patch.
These are things I didn't think to include at the time but which
clearly belonged there.
If an autosuspend fails because driver activity races with
the autosuspend call, restart the autosuspend timer.
When a device is resumed by an external request, it counts
as device activity and should update the last_busy time so
that the next autoresume won't occur immediately.

This patch (as882) fixes a problem with the EHCI BIOS handoff. On my
machine, the BIOS configures the controller and the handoff fails,
leaving the controller configured. During resume-from-disk, this
confuses ehci-hcd into thinking that the controller has not been
tampered with.
The problem is fixed by turning off the Configured Flag whenever a
BIOS handoff is attempted, whether it succeeds or not.

This fixes the issue of drivers claiming multiple interfaces. Operations
are stopped as soon as an interface is suspend and resumed only as
all interfaces have been resumed.

Partial fix for bogosity in the ftdi-elan and u132-hcd drivers ... these
have no business including with the internals of other drivers, much less
doing so in a broken way!!

The Sitecom WL-117 is another "driverless" ZD1211 device where the virtual
windows driver CD must be ejected before the WLAN device appears.
zd1211rw takes care of the ejecting, but usb-storage must be told not to claim
the device.

A bug in the ov7670 sensor causes it to introduce noise unless the CLKRC
register is rewritten *after* setting the image mode. Naturally,
resetting CLKRC in this way will cause other modes to fail. So
carefully poke the register only when indicated.

The proper method for powering down the sensor on OLPC systems has
changed somewhat; in particular, the sensor must be powered down
completely (rather than simply told to power down) or the associated
"camera active" LED will stay on.

dvb-core is not started early enough when device drivers that use dvb are
compiled in so dvb_register_device fails (silently) since dvb_class is
NULL, this runs dvb_init using subsys_initcall instead of module_init.
dvb_register_device will now check the return value of class_device_create.

Reverted the change to struct v4l2_pix_format. I completely missed that
this struct was used by existing ioctls so that changing it broke the ABI.
I will have to think of another way of setting the top/left coordinates
but for now this change is reverted to preserve compatibility.

Prevent legacy drivers from issuing uevents for device creation/removal,
so that userspace can't cause modprobing loops for them. This became a
problem for some legacy PC drivers. I can't easily see it becoming an
issue with I2C legacy drivers, but consistency-in-paranoia seems likely
to be a good thing here. For usable i2c-level driver model uevents, just
switch to a new-style driver.
