From 68bf9d10b0f0248d44e62d38d4e7a8fc5b409599 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 4 Sep 2016 10:43:53 -0300 Subject: [PATCH] mb86a20s: fix demod settings commit 505a0ea706fc1db4381baa6c6bd2e596e730a55e upstream. With the current settings, only one channel locks properly. That's likely because, when this driver was written, Brazil were still using experimental transmissions. Change it to reproduce the settings used by the newer drivers. That makes it lock on other channels. Tested with both PixelView SBTVD Hybrid (cx231xx-based) and C3Tech Digital Duo HDTV/SDTV (em28xx-based) devices.
