I'm not quite sure how that solves the issue with replacing the firmware
image. The driver will still request the same firmware on rebind, so the
only way to have a different firmware loaded would be to replace the
file. That sounds sub-optimal. But it's not very important at this stage
so it can be deferred until (and if) it becomes a real issue.

Yes, thanks very much for confirming.
