It is what it is.

Just for my understanding of what happens next....please correct me if I
have anything wrong:

 - platform_profile gets pulled from ACPI for 5.11

 - platform_profile gets updated to add this data/pointer implementation
and goes into 5.12. Jiaxun, let me know if you're happy with following
up on that based on Hans suggestions, If you are pushed for time let me
know and I'll happily help out/implement/test as required. I sadly don't
have any ideapads but very happy to support your efforts any way I can.

 - Can we get the x86 portion done at the same time or does that end up
going to 5.13? I had been looking at the ideapad_laptop.c patch and have
some concerns there as Jiaxun's patch is essentially a duplicate of what
I implemented in thinkpad_acpi.c which doesn't seem to be ideal
(especially as there is a V6 version of DYTC coming out this year). I
haven't had time to look at code to consider better alternatives though...
