[PATCH] DVB: Revamp of the TTUSB-DEC driver

 - Alter hotplug firmware naming to fit in with dvb standard.
 - Use the hotplug firmware loader for 2.6 kernels instead of compiling
   the firmware into the module. 
 - Integrate frontend into ttusb_dec module and remove pseudo-i2c bits,
   move ttusb_dec header into source file.
 - Rudimentary section filter support (enough for scan).

 	  The DEC devices require firmware in order to boot into a mode in

-	  The firmware can be obtained and put into the default

-
-	    wget http://hauppauge.lightpath.net/de/dec215a.exe
