Running the coccinelle script produced:

  $ spatch \
    --macro-file scripts/cocci-macro-file.h --include-headers \
    --sp-file scripts/coccinelle/find-missing-error_propagate.cocci \
    --keep-comments --smpl-spacing --dir .
  HANDLING: ./migration/colo.c
  [[manual check required: error_propagate() might be missing in migrate_set_block_enabled() ./migration/colo.c:439:4]]

Add the missing error_propagate() after review.
