You asked for a changelog after the cutter, although it really seems
unnecessary to me here as it's repetitive in nature with comment above.

So update the first sentence in the comment to be:
The "BOSC0200" identifier used here is not...

This seems to be a stylistic preference on whether or not to include this
long comment inside of the ACPI match table or not. Stylistically, my
preference would be to include it directly above the match table and not
inside of it. I will wait for Jonathan Cameron's comments about what to do
here.
