Thanks for the report.

kbuild fails to create the .tmp_version directory in the
directory where the module is being built.
The reason to create it there is to avoid trying to write in a RO
kernel src directory. And also to avoid cluttering up the .tmp_versions
directory for the kernel if you build more than one module.
