Thanks, I have no objection against this patch:

Reviewed-by: Hans de Goede <hdegoede@redhat.com>

But this feels like it will become a game of whack-a-mole.

Mark can you reach out to the ThinkPad firmware team and
figure out if there is some supported way to automatically detect
this ?

Regards,

Hans

These are all older platforms and we're not expecting to see this on any newer platforms...if it shows up it's because they messed up (there is a spec and they're supposed to follow it).
Vishnu did review with the FW team which platforms had used this implementation, and we believe the list below to be complete.

Vishnu, please correct me if you've heard otherwise.

As a note, I did review this during an internal review, before Vishnu pushed it, so I'll add:

This is confirmed by the FW team.
The list of systems is complete and no more systems are expected (as of now).

Thank you for your contribution, it has been applied to my local
review-ilpo branch. Note it will show up in the public
platform-drivers-x86/review-ilpo branch only once I've pushed my
local branch there, which might take a while.
