Subject: [PATCH v2 0/3] drm/amdgpu: Fix suspend/resume issues with MST

Fix the suspend/issues that Jerry Zuo found in amdgpu, and add some
compiler warnings for drivers ignoring the return code of
drm_dp_mst_topology_mgr_resume() to help ensure we don't need to fix
this again in the future for someone else's driver.

Cc: Jerry Zuo <Jerry.Zuo@....com>

Lyude Paul (3):
  drm/amdgpu: Don't ignore rc from drm_dp_mst_topology_mgr_resume()
  drm/amdgpu: Don't fail resume process if resuming atomic state fails
  drm/dp_mst: Add __must_check to drm_dp_mst_topology_mgr_resume()
