From db4175ae2095634dbecd4c847da439f9c83e1b3b Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Fri, 4 Jul 2014 05:44:39 -0300 Subject: [media] tda10071: force modulation to QPSK on DVB-S Only supported modulation for DVB-S is QPSK. Modulation parameter contains invalid value for DVB-S on some cases, which leads driver refusing tuning attempt. Due to that, hard code modulation to QPSK in case of DVB-S.
