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.
The list of commits applied:
[1/1] platform/x86: intel_ips: fix kernel-doc formatting
