The pvrusb2 driver resolution limits are now programmed the following
way, based on empirical measurements of the hardware:
  Vertical   max: 480 for NTSC, 576 otherwise
  Vertical   min: 75 for 24xxx, 17 otherwise
  Horizontal max: 720
  Horizontal min: 720 for 24xxx, 19 otherwise

Support for 24xxx devices was previously explicitly bracketed with
CONFIG_VIDEO_PVRUSB2_24XXX inside the code because we didn't trust the
stability of these changes.  We trust it now; so there's no reason to
leave this out of the driver anymore.

Scaling were not working fine;
Some reserved registers were wrong;
On some situations, saa7115 were not properly being initializated.
Removed some duplicated code.

The VIDIOC_G_SLICED_VBI_CAP needs to receive the v4l2_buf_type field before
it can return a result. Hence this ioctl must be IOWR, not IOR. Since this
ioctl is still marked experimental we can make this change.

Adjust temporal filter if necessary. The problem with the temporal
filter is that it works well with full resolution capturing, but
not when the capture window is scaled (the filter introduces
a ghosting effect). So if the capture window changed, and there is
no updated filter value, then the filter is set depending on whether
the new window is full resolution or not.
For full resolution a setting of 8 really improves the video
quality, especially if the original video quality is suboptimal. 
Also report VBI Format in VIDIOC_LOG_STATUS, it was missing.

This patch adds the capability of choicing between autoselecting the

Several audio/video encoders/decoders were just bound as if they were 
part of the core driver.
In fact, they are generic enough to be used by other drivers as well, 
since they use I2C event bus to communicate.

when checking the -Wextra signedness warnings issued by gcc 4.1
I came across this one:
drivers/media/video/vivi.c:1001: warning: comparison of unsigned expression < 0 is always false
Since videobuf_reqbufs() returns negative values on errors the current
code does no real error checking since gcc removes the comparison.
This patch fixes this issue by making ret a normal, signed integer.

Several changes at register stuff were done since commit
b45009b0, but I've forgot
to add the copyright line for this. Those changes allowed
cx88 to have multiple tuners, allowing it to support hardware with
separated radio and video tuners. It also allows binding a tuner to an
