I applied the first patch on top of v7.2 for you to merge into your
subsystem trees as base for applying the patch(es) from this series that
should go via your tree.

Find it at

  https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git tags/devm_notifier_chain_register-for-7.3

This tag only contains this single commit e38b9eda475f ("notifier: add
device-managed registration APIs"). I intend to include it in my PR for
v7.3-rc1, feel free to do the same.

Best regards
Uwe
