Indeed, thanks.

I searched the git log for a bit, looking for ideas.  Every commit I
found that renames a Kconfig option settles for doing just that, without
any further provisions to make some kind of automatic transition happen.
That being said, if there is anything I can do to make it easier for the
user to notice this change, I would be happy to hear about it.

Ah, sure, thanks.  It seems this pattern has changed since the last time
I submitted a patch for drivers/platform/x86.

I will be glad to rip it out in v2, thanks.
