Agreed, I'd propose changing it to:

  The SPDX and verbose license text are redundant, however in this case
  the verbose license indicates a GPL v2 only while SPDX specifies v2+.
  Remove the verbose license and correct SPDX to the more restricted
  version.

I can update on commit unless Cai wishes to respin with different
wording.  Thanks,

Alex
