That is up to Martin, given that he is the author, as to what he wants
to mark this as.  Odd that it missed the big "fix up all files with no
license information" sweep.

Philippe, how did we miss this one?

That is what Linus wants, see the thread on lkml in the past few hours
for his reasoning here.

At this time, no, it's not a simple solution as it gets messy quickly
(multiple c files make up modulues, what about .h files, etc...)

I agree, but now that we are getting SPDX tags, we can fix up all of the
mismatches in MODULE_LICENSE() strings, of which there are a lot.
