From d1d9d0e1724d6a7123b4280fdf6630ae70f96c9c Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Tue, 4 Dec 2018 10:04:41 -0800 Subject: [PATCH] drm/msm: Only add available components When trying to get the display up on my sdm845 board I noticed that the display wouldn't probe if I had the dsi1 node marked as "disabled" even though my board doesn't use dsi1. It looks like the msm code adds all nodes to its list of components even if they are disabled. I believe this doesn't work because all registered components need to come up before we finish probing. Let's do like other DRM code and only add available components.
