You've also included the minor unrelated tweak to check for erorrs
with "err < 0" rather than "err" that has the incredibly small chance
to affect behavior, making this not a 100% noop change.
I don't personally care that much since it's terribly unlikely to
affect anything. ...but you get a 1-line better diffstat if you don't
change it and it's unlikely to matter much either way...
