From ef2fb46b6d7ed9df5906a3c76c9c4673355cd339 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Wed, 3 Sep 2014 23:30:44 -0300 Subject: [PATCH] [media] af9033: remove all DVBv3 stat calculation logic Statistics are now calculated for DVBv5 and those DVBv5 values are returned for legacy DVBv3 calls also. So we could remove all old statistics calculation logic.
