The attached patch modifies the em28xx driver so that there can be ioctls from
multiple different threads.

This is necessary for capture apps like MPlayer that use different threads for
capturing and channel tuning.

Now the locking is only done for the ioctls that change properties of the
device or access the i2c bus.

It also removes some locks that look unnecessary:

In em28xx_init_dev:
  the videodevice is not registered yet so nothing can access the hardware
 meanwhile, the device struct is not assigned to the interface yet so no race
 with disconnect is possible

In em28xx_release_resources:
  it gets only called when dev->lock is already held

V4L/DVB (6508): ttpci: Rework Kconfig menus and Makefile

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.

V4L/DVB (6451): v4l2: add support for bus-based I2C drivers

Two new headers were added: one for I2C drivers that are only used
by V4L2 drivers converted to the new bus-based I2C API, and one that
can be used by both converted and unconverted drivers (at the expense of
some additional overhead).

To support the legacy I2C API a helper function was added to v4l2-common.c.

These headers take care of all the 'boilerplate' code that all V4L2 I2C drivers
have in common and will automatically support the bus-based I2C API introduced
in kernel 2.6.22.

V4L/DVB (6447): tuner: add i2c_gate_ctrl function to struct analog_tuner_ops

In some designs, the tuner silicon may be on an i2c bus behind an i2c gate,
controlled by the analog demodulator.  We already have a method to control
such i2c gates when they are controlled by the digital demodulator, but in
some hybrid designs, there may be an i2c gate controlled by each demodulator.

For example, when in analog tuning mode, one would access the tuner by opening
the i2c gate controlled by the analog demodulator, while when in digital
tuning mode, one would access the tuner by opening the i2c gate controlled by
the digital demodulator.

We must add this callback function to analog_tuner_ops in order to handle
such configurations.
