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. If we want to check error after errp-function call, we need to introduce local_err and than propagate it to errp. Instead, use ERRP_AUTO_PROPAGATE macro, benefits are: 1. No need of explicit error_propagate call 2. No need of explicit local_err variable: use errp directly 3. ERRP_AUTO_PROPAGATE leaves errp as is if it's not NULL or &error_fatel, this means that we don't break error_abort (we'll abort on error_set, not on error_propagate) This commit (together with its neighbors) was generated by for f in $(git grep -l errp \*.[ch]); do \ spatch --sp-file scripts/coccinelle/auto-propagated-errp.cocci \ --macro-file scripts/cocci-macro-file.h --in-place --no-show-diff $f; \ done; then fix a bit of compilation problems: coccinelle for some reason leaves several f() { ... goto out; ... out: } patterns, with "out:" at function end. then ./python/commit-per-subsystem.py MAINTAINERS "$(< 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.
