I agree the transparant workaround attitude is a problem, as a v4l2 kernel
developer I'm a big fan of fixing kernel bugs where possible. At a minimum any
driver issues which need workarounds should be actively reported upstream, so
that they can be fixed in newer kernels.

Talking about this, I was a bit baffled by the s_fmt fallback path in
get_nearest_size, do you know if any devices which actually need that ? AFAIK
ALL drivers should support try_fmt just fine.
