Subject: Re: [PATCH v8 0/3] Add of-graph helpers to loop over endpoints and find ports by id

Hi Philipp and all,

This series has been around for a long time, it seems to be time to get it 
merged.

What's the plan ? If we wait for the v4.1 merge window there's a chance we'll 
get more conflicts, especially on patch 1/3. Could it be merged in v4.0-rc to 
avoid that ?
