Calling gspca_set_alt0() in gspca_dev_probe() is not needed as gspca_set_alt0()
will do nothing because gspca_dev->alt is always zero at that time.

The video_device::minor field is used where it shouldn't, either to

- test for error conditions that can't happen anymore with the current
  v4l-dvb core,
- store the value in a driver private field that isn't used anymore,
- check the video device type where video_device::vfl_type should be
  used, or
- create the name of a kernel thread that should get a stable name.

Remove or fix those use cases.

Now that the video_device registration is tested using
video_is_registered(), drivers don't need to initialize the
video_device::minor field to -1 anymore.

Remove those unneeded assignments.

Instead of using the minor number in kernel log messages, use the device
node name as returned by the video_device_node_name() function. This
makes debug, informational and error messages easier to understand for
end users.

Fix all device drivers to use the video_drvdata function instead of
maintaining a local list of minor to private data mappings. Call
video_set_drvdata to register the driver private pointer when not
already done.

Where applicable, the local list of mappings is completely removed when
it becomes unused.

Replace the video_is_unregistered function by a video_is_registered
function. The V4L2_FL_UNREGISTERED flag is replaced by a
V4L2_FL_REGISTERED flag.

This change makes the video_is_registered function return coherent
results when called on an initialize but not yet registered video_device
instance. The function can now be used instead of checking
video_device::minor.

Currently, the IR table is initialized by calling ir_input_init(). However,
this function doesn't return any error code, nor has a function to be called
when de-initializing the IR's.

Change the return argment to integer and make sure that each driver will
handle the error code. Also adds a function to free any resources that may
be allocating there: ir_input_free().

Modifies the IR table for HVR-950 to use the newer Hauppauge RC5 table,
and adds the RC5 address to the functions that get the scancode for this
device.

It is easy to add support for all other RC5 IR's on em2880 boards, but
the scancode table needs to be re-generated. So, keep using the old
7bits tables while we don't have all tables converted.

Also, the 7bits tables are still used on other drivers, so this small
patch needs to be ported to all drivers.

Adds support to VC211A em2800 card. As this board doesn't have eeprom,
and uses a common set of i2c address, it has no way to add any
autodetection for it.

The patch were tested by me and by Raimundo on his board. Thanks to
those tests, several bugs related to em2800 support were corrected.

Since em2800 can't support 720x480 / 720x576, the driver used to reduce
the scale to half the size on those chips. As the proper fix were
applied, reducing the maximum horizontal resolution to 640, this hack
can be removed.

With em2800 hardware, AC97 hardware can be detected even when it doesn't
exist. If, after probing for AC97, the driver won't find a companion
chip, simply prevents the load of the audio modules.

Due to hardware limitation, em2800 chips can't work at resolutions
higher than 640x576, since the URB packet size is not enough.

The effect is that the image looses packages and shows a distortion
along the vertical axes.
