if (state)

if (1)
However, it makes no sense to keep the if(1).

Clean up the use of structure templates in cx88-i2c and cx88-vp3054-i2c.
For one thing, a real template is supposed to be read-only. And in some
cases it's more efficient to initialize the few fields we need
individually.
This clean-up shrinks cx88-i2c.o by 33% and cx88-vp3054-i2c.o by 49%

The following doesn't make much sense:
drivers/media/video/Kconfig:
...
config TUNER_TEA5761
tristate "TEA 5761 radio tuner (EXPERIMENTAL)"
...
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.

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]
