Merge branch 'tipc-next' 



Erik Hugne says:

====================
tipc: bug fix and some improvements

Most important is a fix for a nullptr exception that would occur when
name table subscriptions fail. The remaining patches are performance
improvements and cosmetic changes.

v2: remove unnecessary whitespace in patch #2
====================
