Latest gang submit patches

[Christian König]

Hi guys,

so Trigger found another issues with this series which is now fixed.

Patch #11 is just a shoot into the dark so far, could be that the VCN3/4
problems are now solved. But could as well be that this needs more
investigation.

Bas still has a backtrace with this which I can't figure out why that is
happening, but going to investigate further.

Please review and comment,
Christian.
