From 38b6441e4e75c0b319cfe4d9364c1059fc1e3c2b Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 22 Mar 2017 22:50:58 +0100 Subject: [PATCH] drm/atomic-helper: Remove the backoff hack from set_config Another one bites the dust. Again let's not forget to remove the temporary hidden acquire_ctx assignment, now that we pass this all around explicitly it can go away again.
