From 593a2ce0ae22188538d27933236a6acab57a0e65 Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Wed, 14 Mar 2012 16:31:26 -0300 Subject: [media] m88rs2000 ver 1.13 Correct deseqc and tuner gain functions Remove incorrect SEC_MINI_B settings-TODO complete this section. Correct break and remove return -EINVAL within set tone. It appears there is a bug that occasionally something other than ON/OFF is sent stalling the driver. Just continue and write back registers. Set register b2 in setup. This is the set voltage pin which isn't used in lmedm04 driver but it is always set to 0x1. Correct the if statements in set_tuner_rf.
