From 3569476dcebc7d6154815239ec982dee77511581 Mon Sep 17 00:00:00 2001 From: Darron Broad Date: Thu, 18 Dec 2008 06:21:51 -0300 Subject: [PATCH] V4L/DVB (9914): cx24116: bugfix: add missing delsys in FEC lookup Delsys was missing when searching for FEC in table. This fixes FEC lookup for DVB-S2 QPSK modulation.
