Remove the subdev_s_std() method from the GPIO subdev.  It appears it was
used in the past to effect the switch back from radio mode to tuner mode,
but it had a side effect that is improper and against the V4L2 spec, when
you were not in radio mode.  Whenever the video stanadrd was changed, the
GPIO audio mux was set back to the tuner audio input, even if you were set
to a Line In input.

Thanks to Ravi A. for doing the troubleshooting to point me right to the
problem.

At least one MT6227 model crashes when receiving a GET_DEF request on the
video probe control. As the various models can't be told apart based on the
descriptors, add a PROBE_DEF quirk to avoid sending the GET_DEF request and
enable the quirk for all models.

. added code to print an error message when buffer is too small to hold frame
data, that is better than just a hard crash. Tested using MAX_FRAME_SIZE =
50000, lots of error messages appeared in /var/log/messages but no crash.

. removed line "f->type = V4L2_BUF_TYPE_VIDEO_CAPTURE;" in
zr364xx_vidioc_try_fmt_vid_cap, it should not be there.

. changes to improve performance (or at least not hurt it): removed some
unneeded debug messages; added macro FULL_DEBUG to enable debug messages in
performance critical places, this macro is disabled by default; removed "if
(frm->lpvbits == NULL)..." in zr364xx_read_video_callback because after
analisying the source code I concluded it will always results to false, so it
is not needed.

. some small code reorganization.

This patch implements changing resolution in zr364xx_vidioc_s_fmt_vid_cap for
zr364xx driver. This version is synced with v4l-dvb as of 20/Jul/2009. Tested
with Creative PC-CAM 880.

OBS: I had to increase MAX_FRAME_SIZE to prevent a hard crash in my notebook
(caps lock blinking) when testing with mplayer, which automatically sets
resolution to the maximum (640x480). Maybe we should add code to auto-detect
frame size to prevent this kind of crash in the future.

This patch implements V4L2_CAP_STREAMING for the zr364xx driver, by
converting the driver to use videobuf. This version is synced with v4l-dvb as
of 15/Jul/2009.

Tested with Creative PC-CAM 880.

It basically:
. implements V4L2_CAP_STREAMING using videobuf;

. re-implements V4L2_CAP_READWRITE using videobuf;

. copies cam->udev->product to the card field of the v4l2_capability struct.
That gives more information to the users about the webcam;

. moves the brightness setting code from before requesting a frame (in
read_frame) to the vidioc_s_ctrl ioctl. This way the brightness code is
executed only when the application requests a change in brightness and
not before every frame read;

. comments part of zr364xx_vidioc_try_fmt_vid_cap that says that Skype +
libv4l do not work.

This patch fixes zr364xx for applications such as mplayer,
Kopete+libv4l and Skype+libv4l can make use of the webcam that comes
with zr364xx chip.

In the past, some devices with saa711x had their parameters controlled
directly inside em28xx driver, instead of using their proper module for
it.

Due to that, the ac97 controls were mixed with saa711x ones.

Older patches removed all saa711x controls, but we still need to control
ac97 devices on em28xx, since we don't have a separate v4l2 device for
it.

The proper way to address is to create a separate ac97 v4l2 device.
While we don't have it, we should clean up the code to allow having a
better view of what is part of em28xx core code and what's due to ac97
control inside it.

As em28xx chip has nothing to do with volume/mute controls, rename those
controls to properly indicate that they control the companion AC97 chip
