From 38f5ddc1bf12887c0abe287de359e853e12fcc19 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 31 Jan 2011 16:25:39 -0300 Subject: [PATCH] [media] cx231xx: Allow some boards to not use I2C port 3 Some devices don't need to use it. So allow to just disable this logic. Having it enabled on some devices cause power management to complain, generating error -71.
