From 147e110bb69a5eaee83bab133d7f7cc4ee050808 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 10 Jul 2011 08:24:26 -0300 Subject: [PATCH] [media] drxk: Fix the antenna switch logic Terratec H5 doesn't require to switch mode, but generates an error due to this logic. Also, GPIO's are board-dependent. So, add it at the board config struct.
