From 482b0e3c2fd73b5c27a4459638b682147ce8119e Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 25 Jul 2017 10:01:20 +0200 Subject: [PATCH] drm: Nuke drm_atomic_helper_connector_set_property It's dead code, the core handles all this directly now. This also allows us to unexport drm_atomic_helper_connector_set_property. The only special case is nouveau which used one function for both pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2 vtables. But amounts to exactly the same. What is rather strange here is how few drivers set this up, I suspect the earlier patch to handle properties in the core did end up fixing a pile of possible issues.
