Other code may need to treat the video decoder sub-device in a special
manner, so this change implements code to recognize when such a
sub-device is connected to the driver, does any special processing for
it, and notes who the device is for future reference.

In order to keep a sub-device from promiscuously attaching to the

This implements a temporary mechanism to "untrack" an i2c module from
the old i2c layer. The v4l2-subdev related code in the driver will
use this to remove a sub-device from the old i2c layer. In the end,
once the old i2c layer is removed, this will also eventually go away.

This is the first step in the effort to move the pvrusb2 driver over
to using the v4l2-subdev framework. This commit involves mainly
splitting apart pvrusb2-i2c-core - part of it is the driver's I2C
adapter driver and the rest is the old i2c module handling logic. The
i2c module handling junk is moved out to pvrusb2-i2c-track and various
header references are correspondingly updated. Yes, this patch has a
huge pile of checkpatch complaints, but I'm NOT going to fix any of
it. Why? First, I'm moving a large chunk of existing code and I'm
not going to spend time adjusting it to match someone's idea of coding
style. Second, in the end I expect all that moved code to go away by
the time the rework is done so wasting time on it now to adhere to the
standard is in the end a large waste of time.

There are several Kconfig items using CUSTOMIZE. Yet, most use the English
writing CUSTOMISE. This generates lots of trouble, because people sometimes type
the Kbuild item different.
Let's standardise every occurrence using the same syntax.

Due to lack of hardware this conversion to v4l2_device/v4l2_subdev is
untested. If all goes well I should be able to test it in about a month,

that this isn't tested.

Using VIDIOC_DBG_S/G_REGISTER is the standard way of reading/writing register
for advanced debugging under v4l2. In addition, using this means that the
cafe_ccic driver doesn't need to have knowledge about the used sensor: the
debug ioctl can be passed on to the sensor if it isn't for the host.

ERROR: "dvb_dummy_fe_ofdm_attach" [drivers/media/video/cx231xx/cx231xx-dvb.ko] undefined!
This happens since cx231xx DVB part still misses the frontend modules.
So, the dummy frontend were used for development. The proper fix is to
implement the DVB modules there, as they will be required.
While this won't happen, lets allow the compilation with or without the
dummy FE testing module.
