There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.

Kconfig items were rearranged, to split V4L/DVB core from their drivers.

The patch extends the default keymap of FlyVIdeo2000 IR remote control so that
this remote may also serve movie & music players in a better way.

I bought a SAA7130 TV tuner with a remote control having 3 additional button
as the default layout, exactly as:

1) labeled "<<<" : key code 0x19, may be used as "backward"in MPlayer,XMMS etc

2) labeled ">>>" : key code 0x1f, may be used as "forward"...

3) not labeled : key code 0x0a, may be used as "pause"...

Once have added these code definitions to the kernel, me got all these
operations available for viewing movies & listening music.

As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.

This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.

After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.

This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.

Video_device_alloc returns the result of a kzalloc.  In this case, the
value is stored in a local variable which is not copied elsewhere before
the point of the error return (video_register_device does not save its
first argument anywhere if it returns a negative value).  Thus, a
video_device_release it needed before the error return.

The problem was found using the following semantic match.

This change adds support for 4 extra keys on the remote currently being
shipped by leadtek with their "WinFast TV2000 XP/Expert" and
"WinFast PVR2000" cards. The remote P/N seems to be Y04G0033 and
you can see a picture of it here: http://lespinasse.org/y04g0033.jpg

The extra keys are at the bottom and are labeled MCE +VOL, -VOL, +CH, -CH.
I chose to map them to the F21-F24 keycodes, following the precedent of
ir_codes_gotview7135[], so as to differentiate these 'MCE' keys from the
other +VOL, -VOL, +CH, -CH 'arrow' keys higher up on the remote.

The ttpci Kconfig file has bugs that cause it to fail in certain Kconfig
situations.  The basic problem is that it selects certain drivers, but does
not depend on the dependencies of those drivers.

See http://article.gmane.org/gmane.comp.video.video4linux/35072

Using the Kconfig file also has some annoyances.  For instance one can't turn
off AV7110 support unless you go down several options and first turn off
budget-patch support.  Normally user selectable drivers are not forced on like
this.

The "AV7110 cards with Budget Patch" option is disabled if "Budget cards"
isn't on.  Normally a driver appears nested under a driver it depends on, but
since drivers that don't depend on "Budget cards" are between the two options,
the config programs can't display the tree correctly.

The Makefile has an issue too.  Some modules, ttpci-eeprom and budget-core,
appear in the Makefile under several different config symbols.  If more than
one of these symbols is on, they will get added the to list of objects
multiple times.  The normal convention is to have a config symbol just the
common object(s) and have the users of the that object either depend on or
select that config symbol.

This patch fixes all these issues.  ttpci-eepom is under a new config symbol,
and so is the budget-core module.  The four different budget card types appear
as sub-drivers under a main "SAA7146 DVB cards" option.  Turning on
budget-patch doesn't force AV7110.  Drivers using SAA7146_VV have the
necessary VIDEO_DEV dependency, so that it isn't possible to select SAA7146_VV
without V4L being on.

I added saa7146_vmalloc_destroy_pgtable() which frees the resources
allocated by saa7146_vmalloc_build_pgtable() and updated the callers in
budget-core.c and av7110.c. I have also been through the updated
functions and updated the error paths to ensure they free all allocated
resources on error.
I also realised that there are other callers to saa7146_pgtable_free()
which did not have any sg DMA mapped so it seems wrong to add the
pci_unmap_sg() into that function. Instead I created
saa7146_vmalloc_destroy_pgtable() to do this.
Also included in this patch are the previous fixes for pci_unmap_sg()
and syncing the PCI streamed data to work with a SWIOTLB and match the
requirements documented in DMA-API.txt.
