[linux-dvb] LeadTek WinFast DTV Dongle patch

Hi,

How do I get a patch incorporated into the dvb kernel section ?

After recently purchasing a LeadTek WinFast DTV Dongle I rapidly
discovered it was the variant that was not recognized in the kernel

i.e. as previously reported at:
http://www.linuxtv.org/pipermail/linux-dvb/2007-December/022373.html
http://www.linuxtv.org/pipermail/linux-dvb/2008-January/023175.html

its device ids are: (lsusb)
ID 0413:6f01 Leadtek Research, Inc.

Rather than make the changes suggested by previous posters I set about
making a script and associated kernel patches to automatically do this.
My motivation was simple: I use a laptop with an ATI graphics card and
fedora 8. I find the best drivers for this card are currently from Livna
and are updated monthly (and changes are significant at the moment i.e.
see the phoronix forum). So I would need to do this repeatedly. 

In my patch I add an identifier (USB_PID_WINFAST_DTV_DONGLE_STK7700P_B)
and modify the table appropriately

When I plug it in I now see in my messages log
kernel: usb 1-4: new high speed USB device using ehci_hcd and address 9
kernel: usb 1-4: configuration #1 chosen from 1 choice
kernel: dib0700: loaded with support for 2 different device-types

kernel: dvb-usb: Leadtek Winfast DTV Dongle B (STK7700P based)

My kernel patch ( other scripts to patch the Fedora 8 src rpm's
available on request)
