Otherwise hint will not be appended in case of errp == &fatal_err (program will exit before error_append_hint() call). Fix such cases. This commit (together with its neighbors) was generated by git grep -l 'error_append_hint(errp' | while read f; do \ spatch --sp-file scripts/coccinelle/fix-error_append_hint-usage.cocci \ --in-place $f; done and then ./python/commit-per-subsystem.py MAINTAINERS "$(< auto-msg)" (auto-msg was a file with this commit message) Still, for backporting it may be more comfortable to use only the first command and then do one huge commit.
