In scmi_devm_notifier_unregister(), the notifier-block argument was ignored
and never passed to devres_release(). As a result, the function always
returned -ENOENT and failed to unregister the notifier.
Drivers that depend on this helper for teardown could therefore hit
unexpected failures, including kernel panics.
Commit 264a2c520628 ("firmware: arm_scmi: Simplify scmi_devm_notifier_unregister")
removed the faulty code path during refactoring and hence this fix is not
required upstream.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
