Instead of splitting the conversion into a module among many patches,
I'd do it in one go. With one patch we get a working module instead
of a half-baked one half way through the series.

The subject could say "Convert X driver from builtin to module". And
instead of "migrate to module_platform_driver", the body could say
"convert to module by switching to module_platform_driver, and adding
missing MODULE_* statements". I believe this constitutes one logical
change. Maybe the accompanying Kconfig change should be included as
well?

Why the name change? If you do change the name, could you also change
the of match table's name as well to be consistent, and also mention
the change in the commit log?

I'd just leave it alone though.
