Recently I discovered my project of mine (call it A), was cloned by another project (call it M) to create a port for a different platform.
"A" was originally licensed as MIT, but has since been relicensed as MIT/Apache. "M", however, was created by copy-pasting all source files in "A", without including the license. "M" is licensed as MIT.
There are a handful of bug fixes (mostly one-liners) in this port that I'd like to include upstream. How do I include these while maintaining a valid license?
