Pull SPDX updates from Greg KH:
"Here are some SPDX license marker changes.
The SPDX-labeling effort has started to pick up again, so here are
some changes for various parts of the tree that are related to this
effort.
Included in here are:
- freevxfs license updates
- spihash.c license cleanups
- spdxcheck script updates to make things easier to work with going
forward
All of the license updates came from the original authors/copyright
holders of the code involved.
All of these have been in linux-next for weeks with no reported
issues"
