Here are some SPDX-specific changes for 5.10-rc1.
They include:
- driver fixes to make spdxcheck.pl work properly
- add GFDL licenses as "deprecated" but required due to some of
our documentation using them
- add Zlib license as "deprecated" but required because we have
code with this license in the tree.
- convert some drivers to have SPDX identifiers that previously
didn't have them.
All have been in linux-next for a very long time with no reported
issues.
