From 793927372626bae48b32db24dddde40d73923a9c Mon Sep 17 00:00:00 2001 From: Darron Broad Date: Thu, 18 Dec 2008 06:28:35 -0300 Subject: V4L/DVB (9918): cx88: advise/acquire clean-up for HVR-1300/3000/4000 This cleans-up the advise/acquire methods. This has been tested on the hvr-1300/4000 and assumed to be correct on the hvr-3000. This update also fixes analogue tuning on the hvr-1300 when in blackbird mode.
