Some ioctls have structs that are a different size depending on what type
of buffer is being used. If the buffer type leaves a field unused or has
padding space at the end, this space should be zeroed out.
The problems with S_FMT and REQBUFS were original identified and patched by
Márton Németh <nm127@freemail.hu>.

From: Trent Piepho <xyzzy@speakeasy.org>
For a number of different ioctls, the v4l2-ioctl code checks that the
passed buffer type is supported by the driver. It did this by checking
that the driver defined a method for the try_fmt handler for that buffer
type. However, try_fmt is optional and a driver might not provide it even
though it does support that type. So use g_fmt instead, since that isn't
optional.
This should fix a problem with VBI capture with saa7146.

If someone requests a format at fmt->index == (unsigned)-1 and the first
format in the array doesn't have the requested type then num will still be
-1 when it's compared to fmt->index and there will appear to be a match.
Restructure the loop so this can't happen. It's simpler this way too. The
unnecessary check for (unsigned)fmt->index < 0 found by Roel Kluin
<roel.kluin@gmail.com> is removed this way too.

USB: add reset endpoint operations
Wireless USB endpoint state has a sequence number and a current
window and not just a single toggle bit. So allow HCDs to provide a
endpoint_reset method and call this or clear the software toggles as
required (after a clear halt, set configuration etc.).
usb_settoggle() and friends are then HCD internal and are moved into
core/hcd.h and all device drivers call usb_reset_endpoint() instead.
If the device endpoint state has been reset (with a clear halt) but
the host endpoint state has not then subsequent data transfers will
not complete. The device will only work again after it is reset or
disconnected.

A regression was introduced in hg changeset 33810c734a0d, which resulted in
a kernel panic whenever the device was disconnected from USB. The call to
4l2_device_register() was overwriting the pointer for usb_set_intfdata(), so
when au0828_usb_disconnect() was called, the usb_get_intfdata() returned a
pointer to the v4l2_device instead of the au0828_dev structure.

Toggle the AI1 mux when changing the CX18_AUDIO_ENABLE register. It's hard to
reliably tell when we have written to this register successfully unless we
change some bits we know we can read back. The AI mux bits always read back
what we wrote to them, so force them to toggle whenever we have to write to
the register, so we can tell we wrote to the register successfully.
This change was prompted by users experiencing broadcast audio decoding
problems after the cx18 module loads for the first time.

Add code to verify the cx18-av-core digitizer firmware loads correctly. The
verification function reads back and compares the firmware bytes loaded
into the A/V core. The result of the verification is only used to log a
message in the system log.
This change was prompted by users with multiple card setups that have problems
with broadcast audio decoding the first time the cx18 module is loaded.

With the transition of soc-camera to become a platform driver and to the
v4l2-subdev framework the initialisation order becomes important. In case
of a static build clients (i2c) drivers have to be available when host
drivers are probed. Moving host drivers down in the Makefile achieves the
desired order.

Currently pcm990 camera bus-width management functions request a GPIO and never
free it again. With this approach the GPIO extender driver cannot be unloaded
once camera drivers have been loaded, also unloading theb i2c-pxa bus driver
produces errors, because the GPIO extender driver cannot unregister properly.
Another problem is, that if camera drivers are once loaded before the GPIO
extender driver, the platform code marks the GPIO unavailable and only a reboot
helps to recover. Adding an explicit free_bus method and using it in mt9m001
and mt9v022 drivers fixes these problems.

Also, use implicit rules instead of explicit, in order to simplify the
