From b79c6df705e02b5dcb0e9360a15b28373813fec1 Mon Sep 17 00:00:00 2001 From: Andreas Regel Date: Tue, 5 Jan 2010 19:18:52 -0300 Subject: [PATCH] V4L/DVB (13974): [STV090x] Fix locking reliabilty issues in automatic mode. In automatic S/S2 detection mode, locking of a DVB-S transponder could fail when coming from a DVB-S2 transponder. This change fixes the issue by first disabling DVB-S and DVB-S2 mode before enabling it again.
