From bfe927647253ab3a86be16320baa1579518c6786 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Wed, 17 Jan 2024 17:00:35 +0000 Subject: [PATCH] drm/vc4: Fix atomic_async_check to call the right mode_set function vc4_plane_atomic_async_check was always calling vc4_plane_mode_set to validate and generate the dlist for the check. If async_check decided it had to fall back to a sync commit, then this GEN4/5 dlist could get used on GEN6. Call either vc4_plane_mode_set or vc6_plane_mode_set as appropriate.
