There are still more places where DVB_FE_CUSTOMIZE is used, instead of
DVB_FE_CUSTOMISE.

The name of the option is DVB_FE_CUSTOMISE. However, on a few places, a wrong
name were used, due to a typo (DVB_FE_CUSTOMIZE).

Dont pass devptr in xc5000_attach, dont store it in xc5000_priv.
This pointer is passed into the tuner_callback function, which always
expects a pointer to fe->dvb->priv or i2c_adapter->algo_data.

This prevents future possible bugs in new drivers, such as using a "devptr"
other that the standard fe->dvb->priv in a DVB driver.

Explicitly set 6 MHz IF frequency for VSB and QAM in
hauppauge_hvr950q_config.

The default value is 6 MHz, so this patch doesn't change anything --
this only improves code readability and may prevent future bugs.

This code is irrelevant to this driver and should be removed.  This was
copied from a hack in cx88-dvb.c, which prevents noise coming from the
analog tuner (via an audio patch cable from the pci card to the sound
hardware) when in digital mode by muting the tda988x.  This issue does
not apply to this USB hybrid chip design, where a single piece of
silicon handles both analog and digital demodulation.

The current code passes a context pointer in the xc5000_config struct.
This context pointer is used in the tuner_callback function, used to
reset the device after firmware download.

The xc5000_config struct is a static structure, whose .priv member was
being assigned before calling xc5000_attach().  If there are more than
one of the same device type installed on a single system, the last one
to assign xc5000_config.priv will "win", and all others will cease to
function properly.

This patch passes the context pointer in xc5000_attach() rather that
storing it within the static struct xc5000_config.

i have not checked it on real hardware and i have not checked whether
the fix is complete.

namespace for all of them.

There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.

Kconfig items were rearranged, to split V4L/DVB core from their drivers.

This patch contains the following cleanups and fixes:
- "debug" is definitely not a good name for a global variable,
  renamed it to "au0828_debug"
  this fixes a compile error with some kernel configurations
- since the module parameter is int the variable shouldn't be unsigned
- remove the {usb,bridge,i2c}_debug module parameters since they are
  already covered by the "debug" module parameter
- remove the unused au0828_bcount
- make the needlessly global i2c_scan static
- make the needlessly global dvb_register() static
