Subject: [PATCH 2/5] V4L/DVB (4840): Budget: diseqc_method module parameter
	for cards with subsystem-id 13c2:1003


From: Oliver Endriss <o.endriss@....de>

New module parameter diseqc_method for cards with subsystem-id 13c2:1003.
- 0: unreliable method, can be used by all board revisions (default)
- 1: reliable method, works for newer board layouts only
The parameter has no effect for cards with other subsystem-ids.
