If we want to add some info to errp (by error_prepend() or error_append_hint()), we must use the ERRP_AUTO_PROPAGATE macro. Otherwise, this info will not be added when errp == &fatal_err (the program will exit prior to the error_append_hint() or error_prepend() call). Fix such cases. This commit (together with its neighbors) was generated by git grep -l 'error_\(append_hint\|prepend\)(errp' | while read f; do \ spatch --sp-file scripts/coccinelle/fix-error-add-info.cocci \ --in-place $f; done and then ./python/commit-per-subsystem.py MAINTAINERS "$(< auto-msg)" (auto-msg was a file with this commit message) and then by hand, for not maintained changed files: git commit -m "<SUB-SYSTEM>: $(< auto-msg)" <FILES> Still, for backporting it may be more comfortable to use only the first command and then do one huge commit.
