I have applied a patch, with a few small changes.

I added an entry in the DEVELOPERS file for this package, so that we
know you are the contact. You will receive e-mails if there are build
failures or CVEs affecting this package, and when new releases are made
upstream (even though I suppose you are the upstream maintainer, so you
should already know!)

Changed to repeat the dependencies of libbpf.

This comment was not correct: you are selecting libbpf, so you don't
need to say that you need it. Instead, I've added our usual comment,
which corresponds to the dependencies inherited from libbpf.

When we have a sha256, md5/sha1 hashes are not needed, so I dropped them.

Applied with those changes, thanks!
