Wrong headline case:
"app/testpmd: fix NULL pointer dereferencing issue": NULL --> null
Missing 'Coverity issue:' tag:
        app/testpmd: fix NULL pointer dereferencing issue

Bernard.

./devtools/check-git-log.sh -1
Wrong headline case:
"app/testpmd: fix NULL pointer dereferencing issue": NULL --> null
[Kalesh]: will fix it.
Missing 'Coverity issue:' tag:
        app/testpmd: fix NULL pointer dereferencing issue
[Kalesh]:  This was found in an internal scan. So there is no Coverity issue tag for this.

If there is no Coverity issue tag for this bug, then best not to mention Coverity in the commit message.
An explanation of the fix should be added to the commit message.

Regards,

Bernard.
