I'm not sure I can add much to help this along, I'm sure Alex has some
internal training,

Once your driver is upstream, it belongs to upstream, you can maintain
it, but you no longer control it 100%, it's a tradeoff, it's not one
companies always understand.

Usually people are fine developing away internally, but once
interaction with other parts of the kernel/subsystem is required they
have the realisation that they needed to work upstream 6 months
earlier.

The best time to interact with upstream was 6 months ago, the second
best time is now.
