[PATCH 132/141] V4L/DVB (3404): Refactored LNBP21 and BSBE1 support

mchehab
2006-03-20T15:17:55Z

From: Oliver Endriss <o.endriss@gmx.de>
Date: 1141129876 -0300

Moved duplicated code to separate files.
LNBP21 stuff rewritten from scratch, BSBE1 copied from av7110.c.
Modified budget driver to use the new routines.
