From 2d84ca215f6d67f9ba7b3d4ab32265e085229662 Mon Sep 17 00:00:00 2001 From: Jose Alberto Reguero Date: Sat, 16 Jul 2011 08:38:13 -0300 Subject: [PATCH] [media] tda827x: improve recection with limit frequencies tda827x is currently taking the demod IF frequency into account while seeking for the proper tuner range. This is wrong, as the demod IF frequency has nothing to do with the tuner PLL.
