From 323a491a29d0bb1e91263ca347cb42c4de28adfc Mon Sep 17 00:00:00 2001 From: Martin Dauskardt Date: Sat, 18 Oct 2008 14:59:09 -0300 Subject: [PATCH] V4L/DVB (9326): ivtv: avoid green flashing when loading ivtv When loading ivtv the TV-out of the PVR-350 will flash green since the saa712x is activated before the MPEG decoder has been initialized. Deactivate the saa712x until the MPEG decoder has been initialized.
