As of commit 37c90d589dc0 ("drm/fb-helper: Fix single-probe color-format
selection"), if no supported color formats are found, it tries to use the
driver provided default, which msm didn't have set and leads to the
following output:
msm_dpu ae01000.display-controller: [drm] bpp/depth value of 32/0 not supported
msm_dpu ae01000.display-controller: [drm] bpp/depth value of 32/0 not supported
msm_dpu ae01000.display-controller: [drm] bpp/depth value of 32/0 not supported
msm_dpu ae01000.display-controller: [drm] No compatible format found
