Of course not, no new users needed.

I haven't discussed it directly. I found the unused __symbol_get_gpl()
myself, but during investigation of wether it was ever used somewhere
found the old patch series suggested by Mauro Carvalho Chehab (in Cc).

Link: https://lore.kernel.org/lkml/5f001015990a76c0da35a4c3cf08e457ec353ab2.1652113087.git.mchehab@kernel.org/

The patch series is from 2022 and not merged. You can take [PATCH v6
1/4] which removes the unused symbol from the link.

Or I can resend v2 with my commit msg. But not sure about how it works
in such a case - will adding Suggested-by tag (if no objections from
Mauro) with the Link be ok?
