Many drivers repeat the same boilerplate when registering notifiers with
device lifetime:

  1. Register the notifier with *_notifier_chain_register()
  2. Check for error
  3. Register a devm action to unregister on teardown
  4. Implement a per-driver static unregister callback

This series adds devm_atomic_notifier_chain_register() and
devm_blocking_notifier_chain_register() that automatically unregister
the notifier when the device is unbound, then converts 11 drivers to use
them.

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.

While I tried to pick up the pwm patch in this series I noticed my
Arithmetic error here 🙄. It should be 7.4 of course. I created

	https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git tags/devm_notifier_chain_register-for-7.4

with a fixed tag message and dropped the 7.3 tag. (Even is someone
already pulled it, nothing bad happens as it points to the same commit.)

Sorry for the confusion.
