From eb47fe8033d6c2013ce47ec44f39fa0092aa8551 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 16 Nov 2015 18:19:53 +0100 Subject: drm: Do not set connector->encoder in drivers An encoder is associated with a connector by the DRM core as a result of setting up a configuration. Drivers using the atomic or legacy helpers should never set up this link, even if it is a static one. While at it, try to catch this kind of error in the future by adding a WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't cover all the cases, since drivers could set this up after attaching. Drivers that use the atomic helpers will get a warning later on, though, so hopefully the two combined cover enough to help people avoid this in the future.
