Always when you fix a bug that was introduced by another commit?

I need the commit reference to check if I need to queue the fix to
current development kernel (i.e. v4.0-rcN).

If someone backports the commit, it's easier to check if the commit is
referenced by a later commit potentially fixing issues in it.

I typically wouldn't know this by looking at a patch. The commit
reference helps. And to squash it into another commit, the reference
helps.

Reducing the burden from the maintainers helps you too in the end!

BR,
