In the past, it was possible to have either DVB or V4L2 core
as module and the other as builtin. Such config never make much
sense, and created several issues in order to make the Kconfig
dependency to work, as all drivers that depend on both (most
TV drivers) would need to be compiled as 'm'. Due to that,
the VIDEO_MEDIA config option were added.
Instead of such weird approach, let's just use the MEDIA_SUPPORT
=y or =m to select if the media subsystem core will be either
builtin or module, simplifying the building system logic.
Also, fix the tuners configuration, by enabling them only if
a tuner is required. So, if just webcam/grabbers support is
selected, no tuner option will be selected. Also, if only digital
TV is selected, no analog tuner support is selected.
That removes the need of using EXPERT customise options, when
analog TV is not selected.

The V4L querystd implementation appears to want to narrow down the
list of available standards by starting with a hardware-supported list
and then attempting to detect which among those are actually
available. Prior to this change in the pvrusb2 driver we started with
all possible standards. With this change in place we instead narrow
to just the standards that we know the hardware can actually support.
For example, this removes the ATSC standards from the list if we
aren't dealing with a hybrid device...

With the transition to ioctl2, the pvrusb2 driver's own standards
enumeration is no longer used. Instead a generic algorithm internal
to v4l is used (which is a great idea - since the pvrusb2
implementation itself was generic anyway). This change ensures that
the v4l algorithm works with the correct set of hardware supported
standards. This resolves a FIXME left behind from the videodev_ioctl2
transition.

control ID
Other aspects of the pvrusb2 driver - including in particular those
dealing with video standards - all use internal control IDs for
uniform access by the interfaces. By exporting the querystd result as
another control ID, uniform access to it becomes available through the
sysfs interface.

In any statically initialized data structure, the compiler is going to
zero any part which is not already explicitly initialized. While we
can take that knowledge overboard and simply avoid initializing
anything that needs to be zero, it's at least a good idea not to
bother zeroing parts that we don't otherwise care about - like
"reserved" fields which may change in the future. Avoiding
initialization of those fields now also avoids possible conflict down
the road.

The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner
instead of a tda18271c1 tuner as used in revision D1E9. To
account for this, we must hardcode the frontend configuration
to use the same IF frequency configuration for both revisions
of the device.
6MHz DVB-T is unaffected by this issue, as the recommended
IF Frequency configuration for 6MHz DVB-T is the same on both
c1 and c2 revisions of the tda18271 tuner.

If V4L2_CAP_DEVICE_CAPS is set, then the new device_caps field is filled with
the capabilities of the opened device node.
The capabilities field traditionally contains the capabilities of the physical
device, being a superset of all capabilities available at the several device
nodes. E.g., if you open /dev/video0, then if it contains VBI caps then that means
that there is a corresponding vbi node as well. And the capabilities field of
both the video and vbi nodes should contain identical caps.
However, it would be very useful to also have a capabilities field that contains
just the caps for the currently open device, hence the new CAP bit and field.

kbuild: introduce ccflags-y, asflags-y and ldflags-y
Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.
Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

The tuner-core subdev requires that the type field of v4l2_tuner is
filled in correctly. This is done in v4l2-ioctl.c, but pvrusb2 doesn't
use that yet, so we have to do it manually based on whether the current
input is radio or not.

The rc-hauppauge-new map is a messy thing, as it bundles 3
different remote controllers as if they were just one,
discarding the address byte. Also, some key maps are wrong.
With the conversion to the new rc-core, it is likely that
most of the devices won't be working properly, as the i2c
driver and the raw decoders are now providing 16 bits for
the remote, instead of just 8.

Add the same "are you ready?" i2c_master_send() poll command to

pvrusb2: Delete sysfs class device as the _very_ last step, after
we're sure that all driver contexts have gone away first. This is
important because it appears that there isn't any protection from a
struct device instance reference a deleted struct class instance. The
assumption in the kernel code appears to be that the class instance is
assumed to be around for the life of the device. So we can't let the
class instance go away until all referencing device instances are
gone; this is ensured by delaying removal of the class instance until
after the driver contexts have all gone away. This bug has been
present for a very long time but it didn't apparently become malignant
until recently (probably because of other changes in the kernel).
