Oh! I should had read this before commenting on the cover letter... sorry...
Anyway I don't believe it make clear that it is not skl... because it means
it started on i9xx, but not that ended on skl... just "plane" was already
good enough imho... but it is really just a comment...
don't take this as a nack anyhow... ;)
