From: Arnd Bergmann <a...@arndb.de>
The newly added code is in an #ifdef, so the variables that
are only used in there cause a warning if CONFIG_DRM_AMD_DC_DCN
is disabled:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c: In function
'amdgpu_dm_atomic_check':
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:9698:43: error:
unused variable 'mst_state' [-Werror=unused-variable]
9698 | struct drm_dp_mst_topology_state *mst_state;
| ^~~~~~~~~
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:9697:41: error:
unused variable 'mgr' [-Werror=unused-variable]
9697 | struct drm_dp_mst_topology_mgr *mgr;
| ^~~
Fixes: c689e1e362ea ("drm/amdgpu/display/mst: Fix mst_state->pbn_div and slot
count assignments")
