- lines with more than 80 columns
- two statements at the same line

V4L/DVB (6593): Fix scode table loading

Xceive 2028/3028 has a concept of scode/dcode.
Scode is a table of 16 values (each with 12 bytes i2c sequence).
Dcode is the entry of Scode table that should be used, given a certain
frequency.

The idea is that, depending on what frequency is selected, and according with a
country-based (or standard-based?) table, the Xceive should be "hacked" to
fine-tune that specific frequency.

By default, Scode=0 is used, for undefined frequencies. Also, Scode=0 seems to
be the most used value.

This patch adds the capability of selecting a scode. However, extra work will
be needed to allow auto-selecting the proper scode, for a given set of
frequencies.

I'm not sure what would be the proper way for implementing the dcode selection.

V4L/DVB (6538): em28xx: fix locking to allow accesses from 2 different threads at the same time

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.
