It's a good idea do keep includes ordered like

+#include <drm/drm_atomic_helper.h>
+#include <drm/drm_vblank.h>
+
+#include "amdgpu.h"
+#include "amdgpu_dm_crtc.h"
+#include "amdgpu_dm_debugfs.h"
+#include "amdgpu_dm_plane.h"
+#include "amdgpu_dm_psr.h"
+#include "amdgpu_dm_trace.h"
+#include "dc.h"

because it's easier to check for duplicates and prevents the need for
fixes like this in the future:
