From b03df0f2b745285c1909f1f4efd6e177c7837c5a Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Mon, 17 Jul 2006 17:15:26 -0300 Subject: Set the Auxiliary Byte when tuning LG H06xF in analog mode From: Michael Krufky With the LG H06xF tuners, an auxiliary byte must be sent after the standard four-byte i2c sequence. The code that does this is currently in the wrong place, causing random bytes to be written to the tuner over i2c in the set_type function. This patch moves this code from set_type to default_set_tv_freq.
