Max gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, Holger Freyther, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/1629 to look at the new patch set (#4). Expand and expose ctrl connection allocation Add function for allocating CTRL connection to public headers and replace call to previous static function with it. Add doxygen docs for this function.
