Ingo Molnar b1912a85b5 media: video: Fix build in saa7164
-tip testing found that the x86 build (64-bit allyesconfig) fails due to:

  LD      vmlinux.o
  drivers/built-in.o:(.bss+0x4b648): multiple definition of `debug'
  arch/x86/built-in.o:(.kprobes.text+0x88): first defined here
  ld: Warning: size of symbol `debug' changed from 90 in
arch/x86/built-in.o to 4 in drivers/built-in.o
 make: *** [vmlinux.o] Error 1

This is because recent saa7164 changes introduced a global symbol
named 'debug'. The x86 platform code already defines a 'debug'
symbol. (which is named in a too generic way as well - but it
can be used nicely to weed out too generic symbols in drivers ;-)

Rename it to saa_debug.

[mchehab@redhat.com: use module_param_named to preserve old name]

Steven Toth 39e469ab6d V4L/DVB (12940): SAA7164: IRQ / message timeout related change
In some cases we're seeing large timeouts on commands. I'm changing the
implementation so that the deferred worker checks the PCI bus for
any messages and signals the waiting caller accordingly. The previous
mechanism was too unreliable.

Steven Toth 443c1228d5 V4L/DVB (12923): SAA7164: Add support for the NXP SAA7164 silicon
This patch adds support for all of the known shipping Hauppauge HVR-2200
and HVR-2250 boards. Digital TV ATSC/QAM and DVB-T is enabled at this
time. Both tuners are supported.

Volatiles and typedefs need rework, the rest is coding style compliant.
