This seems to be completely unfair to Vivien, there is nothing wrong
with his patch series per-se other than he was unfortunate enough he
highlighted something that needs fixing. This was not a serious enough
problem before and it cannot possibly be one now either with just a code
move.

On a general note, we cannot have whoever was the last one to touch a
piece of code that makes us see that this or that said piece of code is
less than ideal be selected as the random victim for doing that cleanup,
this just does not work. I know this is standard practice in Linux and
other open source software (been there before with the USB maintainers),
but this creates only one thing: making you want to runaway and scream
lalalalala.

So let's be pragmatic and maintain a public TODO list for this driver
that people can pick items to fix/cleanup/change that have been
identified as candidates for patches.
