em28xx-dvb.c:
 - Remove unneeded xc3028_ctrl structure.  The driver automatically preserves
   the previous value

tuner-xc2028.c:
 - Make the return type for xc2028_get_reg signed, since all of the callers
   are looking for "< 0" to detect errors.

em28xx-cards.c:
 - Fix reversed val/rst values in both analog_gpio and digital_gpio

 - Fix crash that would was occurring during every analog startup
   while looping over gpio_ctl
 - Remove what appears to be a redundant setting of gpio_ctl->val
 - Don't use OREN538 demodulation for the HVR-950 (prevents ATSC
   scanning from working)

em28xx-dvb.c:
 - Tuner should be in digital mode when issuing the reset
 - Add copyright

The patch extends the default keymap of FlyVIdeo2000 IR remote control so that
this remote may also serve movie & music players in a better way.

I bought a SAA7130 TV tuner with a remote control having 3 additional button
as the default layout, exactly as:

1) labeled "<<<" : key code 0x19, may be used as "backward"in MPlayer,XMMS etc

2) labeled ">>>" : key code 0x1f, may be used as "forward"...

3) not labeled : key code 0x0a, may be used as "pause"...

Once have added these code definitions to the kernel, me got all these
operations available for viewing movies & listening music.

Observation one: ->write_proc and ->data assignments aren't needed. Removed.
Observation two: codecs lists are unprotected. Patch doesn't fix this.
Observation three:
	/proc/videocodecs printout is done to temporary _global_ buffer which
	is freed in between. Consequently, two users hitting this file can
	screwup each other.

Steps to reproduce:

	modprobe videocodec
	while true; do cat /proc/videocodecs &>/dev/null; done &
	while true; do cat /proc/videocodecs &>/dev/null; done &

The fix is switching to seq_files, this removes code, especially some

This patch fixes three related issues and a fourth trivial one:

- Use buffers even if no-one's currently waiting for them (fixes
  underrun issues);

- Don't return incomplete/mangled frames at the start of streaming and
  in the case of buffer underruns;

- Fix an issue which could cause the driver to write to a buffer that's
  been freed after videobuf_queue_cancel is called (exposed by the
  previous two fixes - for some reason, ignoring buffers that weren't
  being waited on worked around the issue);

- Fix a bug which could cause only one field to be filled in the first
  buffer (or first few buffers) after streaming is started.
