[cmake-developers] fixing a bug after topic was merged to master

[Domen Vrankar]

Hi all,

While writing tests for a new topic I found a bug in an older topic
that I wrote.
The that topic was already merged to master (last week) but remote
stage branch still exists.
The fix is trivial - one variable typo.

How can I get the fix both into master and next release candidate branch?
Should I create a new topic and push that to next or should I extend
the old one even though it was already merged to master and push that
one to next?

Thanks,
Domen
