Because that ID is already in use on the Surface Laptop 4 and
potentially other AMD-based laptops that are already available for
purchase. Not having it in stable means that people may have to deal
with some things not working (as this may prevent other drivers relying
on GPIOs from working) until 5.14 is available on their distribution of
choice.

Given the size of this change, I hardly think that's necessary. Which
is, I believe, also why the stable-kernel-rules doc points out that new
device IDs are (generally) allowed.

Regards,
Max
