From 71dfb744bd9e11e765036f8096d7c2c6c19d2b0f Mon Sep 17 00:00:00 2001 From: Carlos Palminha Date: Wed, 10 Feb 2016 12:08:38 +0000 Subject: [PATCH] drm: fixes when i2c encoder slave mode_fixup is null. Avoid i2c slave encoder drivers to copy/paste code to implement functions that will only return true.
