From f1bbb43a667067f24a729df78dc050348b1c7846 Mon Sep 17 00:00:00 2001 From: Ben Backx Date: Sun, 22 Jun 2008 16:00:53 +0200 Subject: [PATCH] firesat: fix DVB-S2 device recognition This only makes sure that a DVB-S2 device is really recognized as a S2, nothing else is added yet. It's using the string containing the model that is stored in the configuration ROM, the older version was using some hardware revision dependent part of the ROM.
