Summary
drm/msm/dpu: cleanup FB if dpu_format_populate_layout fails
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/dpu: cleanup FB if dpuformatpopulate_layout fails

If the dpuformatpopulatelayout() fails, then FB is prepared, but not cleaned up. This ends up leaking the pincount on the GEM object and causes a splat during DRM file closure:
