You're not filling in the 'field' field of struct v4l2_buffer when returning a
frame. It should most likely be FIELD_NONE in your case.

 		fail: v4l2-test-buffers.cpp(884): captureBufs(node, q, m2m_q, frame_count, false)

OK, easy to fix. This will also influence the other two warnings, I assume?

Most likely, yes.

Done. I would say that it's nearly ready for submission now (all tests
from v4l2-compliance -s pass), I still have to sort out all the warnings
from scripts/checkpatch.pl.

On a different note, I'm getting occasional warnings in syslog when I run 
a regular video streaming application (e.g. cheese):

Is there another possible explanation?

No :-)
You are still missing a buffer somewhere. I'd have to see your latest source code
to see what's wrong.

Weirdly enough, the syslog warning/error doesn't seem to occur anymore
since I've fixed the v4l2_buffer field. Perhaps some oddity within cheese?

I'm attaching the current source again for you to maybe have another
look; I will submit a proper patch in the next days.

Thanks again for your help!
Best, Florian
