Here are some SPDX (i.e. licensing) changes for 5.19-rc1
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.
