Otherwise, this info will not be added when errp == &error_fatal (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 then 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_fatal, this means that we don't break error_abort (we'll abort on error_set, not on error_propagate) This commit is generated by command sed -n '/^X86 Xen CPUs$/,/^$/{s/^F: //p}' MAINTAINERS | \ xargs git ls-files | grep '\.[hc]$' | \ xargs spatch \ --sp-file scripts/coccinelle/auto-propagated-errp.cocci \ --macro-file scripts/cocci-macro-file.h \ --in-place --no-show-diff --max-width 80 Reported-by: Kevin Wolf <kw...@redhat.com> Reported-by: Greg Kurz <gr...@kaod.org> Signed-off-by: Vladimir Sementsov-Ogievskiy <vsement...@virtuozzo.com>Reviewed-by: Paul Durrant <p...@xen.org>
