From 9e23f50a762c236049b4965a42d86d55fcdbbfb3 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Wed, 4 Jul 2012 17:36:55 -0300 Subject: [media] drxk: Make the QAM demodulator command parameters configurable Currently there are two different implementations (in the firmware) for the QAM demodulator command: one takes 4 and the other takes 2 parameters. The driver shows an error in dmesg When using the 4-parameter command with firmware that implements the 2-parameter command. Unfortunately this happens every time when chaning the frequency (on DVB-C). This patch simply makes configurable, how many command parameters will be used. All existing drxk_config instances using the "drxk_a3.mc" were updated because this firmware is the only loadable firmware where the QAM demodulator command takes 4 parameters. Some firmwares in the ROM might also use it. The drxk instances in the em28xx-dvb driver were also updated to silence the warnings. If no qam_demod_parameter_count is given in the drxk_config struct, then the correct number of parameters will be auto-detected.
