From eac1fe1050f223d28ebe5bb73b438d82ffd5b675 Mon Sep 17 00:00:00 2001 From: Olivier Grenie Date: Wed, 23 Sep 2009 13:41:27 -0300 Subject: V4L/DVB (13051): DiB7000P: improve rebostness of HAS_LOCK indicator Update the dib7000p: The status is HAS_LOCK only if the demod is able to decode the TPS. Sometimes, there is a TPS data lock, even if the demod is not able to decode it (ex: no RF signal).
