should check whether the passed control ID is valid and return 0 if it 
isn't. Otherwise a for-loop over the control IDs will never end.

dd1e729d63 V4L/DVB (5866): ivtv: fix DMA timeout when capturing VBI + another stream
The VBI DMA is handled in a special way and is marked with a bit.
However, that bit was set at the wrong time and could be cleared
by mistake if a PCM (or other) DMA request would arrive before the
VBI DMA was completed. So on completion of the VBI DMA the driver
no longer knew that that DMA transfer was for VBI data. And this
in turn caused havoc with the card's DMA engine.

...
drivers/media/video/Makefile:
...
ifneq ($(CONFIG_TUNER_TEA5761),)
  tuner-objs += tea5761.o
endif
...
With this setup, TUNER_TEA5761=m is equivalent to TUNER_TEA5761=y.
This patch therefore changes TUNER_TEA5761 to a bool.
The missing dependency on EXPERIMENTAL the prompt text indicates also
gets added by this patch.
Additionally, the Makefile entry can now be written in a more compact way.

ac7dc84584 V4L/DVB (5805): Bttv: Fix problems with probing for non-existent tuners
The bttv driver has code to detect if a tda9887 is present, that was previous
used to auto-load the tda9887 driver.  Now there is no tda9887 driver, so the
code is pointless; it just figures out if it should load the driver and then
does nothing.

For cards that are defined as having no tuner, the init code would still do
i2c probes for various tuner devices and auto-load the tuner module.  That can
be skipped for cards that don't need it.  The code is made to understand that
in addition to 'UNSET', 'TUNER_ABSENT' also means no tuner.

The tuner into printk()s are also made nicer.  Levels are added, INFO or
WARNING, depending on the meaning.  For cards with no tuner, or no tuner
defined, a more informative message is printed.

Card has no tuner, before patch:
bttv0: tuner type=-1
 or
bttv0: tuner type=4

After patch:

bttv0: tuner absent

Card has a tuner, but the type isn't defined, before patch:
bttv0: tuner type=-1

After patch:
bttv0: tuner type unset   [<- also warning now, as the tuner won't work right]
