Subject: devtools: fix check of symbol added as stable API
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=af14b150df78ec46de919ae4a30efbefbcd44c95

devtools: fix check of symbol added as stable API

The incriminated commit broke the detection of new symbols skipping the
EXPERIMENTAL step before entering a stable ABI section.
sed won't return an error, check a null output instead.

Fixes: 3630757803ab ("devtools: accept experimental symbol promotion")
