From 163c9bca101caf000691b56fb3834905e62cbba3 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 27 Jan 2016 08:39:33 -0200 Subject: [PATCH] [media] tuner.h: rename TUNER_PAD_IF_OUTPUT to TUNER_PAD_OUTPUT The output of a tuner is not only IF frequencies. They may also output audio on some of its pins, and may even be a zero-IF tuner, with outputs a baseband. So, rename the PAD name to make it clearer and add a proper documentation about that at tuner.h. No functional changes.
