[linux-dvb] Matrix reloaded Cam working with NOVA-CI !

[Sjoerd Simons <sjoerd@luon.net>]

Hi,
  
  We've got a WinTV-NOVA-CI with a matrix reloaded cam card, the cam didn't work
  at first. After some digging (adjust timeouts and stuff like that), i noticed
  that the card was never reset during the initialisation. Adding a reset
  made the card work :). Patch for this is attached.

  Unfortunately loading the dvb-core.ko without dvb_ca_en50221_debug=1 hangs
  the kernel. And i don't know enough about this stuff to really debug that.
  Alse the location where i added the reset is probably also not really 
  ``correct''

  Sjoerd
