From f6764815358b57c520ea137599e8297479bded4c Mon Sep 17 00:00:00 2001 From: Lyude Paul Date: Tue, 23 Oct 2018 19:12:47 -0400 Subject: [PATCH] drm/dp_mst: Remove all evil duplicate state pointers There's no reason to track the atomic state three times. Unfortunately, this is currently what we're doing, and even worse is that there is only one actually correct state pointer: the one in mst_state->base.state. mgr->state never seems to be used, along with the one in mst_state->state. This confused me for over 4 hours until I realized there was no magic behind these pointers. So, let's save everyone else from the trouble. Signed-off-by: Lyude Paul .
