Removed the switch..case block in blackbird_probe for setting encoder height
based on video standard. All blackbird devices can rely on tvnorm->id to
retrieve this information from the cx2388x video decoder - tuner_formats
should not be used to determine the encoding video standard.

Most uses a tda988[5/6/7] IF demodulator as part of the device.
Having this as a separate stuff makes harder to configure it, since there
are some tda9887 options that are tuner-dependent and should be bound into
tuner-types structures.
This patch merges tda9887 module into tuner. More work is required to make
tuner-types to properly use it.

CX2341X port was always set to 'memory', but 'streaming' is also possible
ivtv uses the memory (DMA) interface with the CX2341X, while pvrusb2 and
cx88-blackbird use the streaming interface. This setting is now selectable
by the driver.

Control processing is often duplicated in the various drivers. Unfortunately,
simple things like the names of controls are often different between drivers,
even though it is the same controls. Adding in the new extended controls and
the need for having control helper functions became apparent.
Several functions have now been added to v4l2-common to do things like
filling the v4l2_queryctrl and v4l2_querymenu structs, to check for
valid control input and to move to the next control when enumerating
over all controls.

The coverity checker detected a use-after-free error in
drivers/media/video/cpia2/cpia2_v4l.c::cpia2_close() (coverity
error #1281).
What happens is that we lock cam->busy_lock, then proceed to free
resources, and in the case of (--cam->open_count == 0) we finish off by
doing a kfree(cam) and then at the end of the function we do a
mutex_unlock(&cam->busy_lock) which will explode since it'll dereference
the free'd `cam' :
...
mutex_lock(&cam->busy_lock);
...
if (--cam->open_count == 0) {
...
if (!cam->present) {
video_unregister_device(dev);
kfree(cam);
}
}
mutex_unlock(&cam->busy_lock); <--- PROBLEM, cam no longer around.
...
Since this only happens in the case of open_count going down to zero I
don't see a problem with just releasing the mutex after unregistering the
device and just before the kfree(). In this case there is nothing around
that we can race against; we are in the release method, open_count is zero,
(!cam->present) and the device has just been unregistered, so letting go of
the mutex at this point looks safe to me.
Patch below to implement that solution.
