I don't understand what happened with this series. lore cannot find
anything for above change-id. b4 diff also fails:
b4 diff '<20240704-tegra210_emcfreq-v4-0-3e450503c555@xxxxxxxxxxxxxxxxxx>'

Could not find lower series to compare against.

Link to v3 does not point to v3, but to some resend. Changelog is
incomplete - mentions only v3, but what happened between v1->v2, v2->v3?

There is canonical way to send patches which makes everything
straightforward (and IMHO easy). It's called b4. But you can just use
git format-patch and git send-email. Whatever you choose, this makes
maintainer life easy.

Way you sent patches is somehow broken, I don't know how, but it does
not make maintainer life easy.

Please reply with changelog and explanation where is original v3.


Best regards,
