Patch that should add support to new tuner.

Description of problem:
Some new tuner prevents the budget-av driver to load for the following version of the mystique CaBiX-C2 dvb-C card:
(lspci output)
04:00.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
        Subsystem: KNC One Device 0028
        Flags: bus master, medium devsel, latency 64, IRQ 11
        Memory at febffc00 (32-bit, non-prefetchable) [size=512]


Version-Release number of selected component (if applicable):
kernel up to 2.6.40-4.fc15


How reproducible:
always

Steps to Reproduce:
1. install card & boot
2. find no /dev/dvb device files.
3. modeprobe budget_av
4. still no /dev/dvb/* files
  
Actual results:
module is loaded, doesn't detect card

Expected results:
module is loaded, should provide /dev/dvb* files


Additional info:
There is a Patch around ( http://www.vdr-portal.de/board16-video-disk-recorder/board5-vdr-konfiguration/p1010445-linux-diff-file-f%C3%BCr-neue-mystique-cabix-c2/#post1010445 ) which quickly adds the changed component's id to the driver budget_av. However, I did not manage to compile the kernel with this modification (lack of time / other dependencies involved) but I suppose the patch should work...

If someone can provide 64-bit rpms I can test if they work for me.

(attached is the diff file from the link).

Kind regards,
Max Imgrund

That patch has broken whitespace and no Signed-off-by line.

If you'd like to work on getting the change upstream, then you could take the patch to the V4L/DVB maintainers.  Also, building your own kernel is detailed here:

Support for this was added with:

which went into the 3.2 kernel.  F15 already contains that patch.
