No, because $root is a git repository in my case (linux-next to be
exact). The problem here is that spdxcheck is ignoring $root and just
assumes that cwd is a linux git repository. And when it is one but not
a linux git repo then I get following error:

FAIL: "Blob or Tree named 'other' not found"
Traceback (most recent call last):
  File "/usr/src/linux-next/scripts/spdxcheck.py", line 234, in <module>
    spdx = read_spdxdata(repo)
  File "/usr/src/linux-next/scripts/spdxcheck.py", line 41, in read_spdxdata
    for el in lictree[d].traverse():
  File "/usr/lib/python2.7/dist-packages/git/objects/tree.py", line
298, in __getitem__
    return self.join(item)
  File "/usr/lib/python2.7/dist-packages/git/objects/tree.py", line 244, in join
    raise KeyError(msg % file)
KeyError: "Blob or Tree named 'other' not found"


Still, your change looks good when $root is pointing to an extracted
tarball with the linux sources and not to a full repository
