After the i2c subdev changes the ordering of initialization changed,
causing a total loss of previous GPIO settings and a loss of DTV.
The generic firmware loading routine has now changed to preserve
GPIO values if the device is cx23885 based (safety) and I've
moved the GPIO configuration from probe() into the cx23885 init
func which is a little clearer and fixes the bug.

Replace printing to magically sized temporary buffer with use
of KERN_CONT for continual printing of eeprom registers dump.

Since deb_info is defined as dprintk, which is conditionally defined
to printk without additional parameters, meaning that deb_info is equivalent
to direct printk (without adding KERN_ facility), we can use KERN_DEBUG and
KERN_CONT in there, eliminating the need for sprintf into temporary buffer
with not easily readable/magical size.

Though it's strange, that deb_info definition uses printk without KERN_
facility and callers don't use it either.

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.

. 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.

In automatic mode every stop event on SDA line ends repetition.
However, in  NetUP Dual card on the same i2c bus we have several devices.
If someone using both adapters to lock simultaneously or working with CAM interface
during lock procedure, it lead to end repetition prematurely quite often.
Set stv0900 i2c repeater to manual mode prevents such situation.

The dvb-pll code should do the same thing that
alps_tdee4_stv0297_tuner_set_params() was doing.  Except the dvb-pll code
will check for tuner presence when attaching, while the old code didn't.

This tuner appears to not be behind the stv0297's I2C gate but is instead
on a different I2C adapter provided by the flexcop chip.  The old code
would turn the I2C gate off each time the tuner was used.  I've changed it
to turn the gate off when the tuner is attached and then disable the gate
control function.  This should result in the gate staying off, which should
be even better.
