#     Merge tag 'spdx-5.2-rc3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
#     
#     Pull SPDX fixes from Greg KH:
#      "Here are just two small patches, that fix up some found SPDX
#       identifier issues.
#     
#       The first patch fixes an error in a previous SPDX fixup patch, that
#       causes build errors when doing 'make clean' on the tree (the fact that
#       almost no one noticed it reflects the fact that kernel developers
#       don't like doing that option very often...)
#     
#       The second patch fixes up a number of places in the tree where people
#       mistyped the string "SPDX-License-Identifier". Given that people can
#       not even type their own name all the time without mistakes, this was
#       bound to happen, and odds are, we will have to add some type of check
#       for this to checkpatch.pl to catch this happening in the future.
#     
#       Both of these have passed testing by 0-day"
