Linux kernel stable tree

There's no real need for callers to resolve ops from a fwnode in order to then pass both to iommu_fwspec_init() - it's simpler and more sensible for that to resolve the ops itself. This in turn means we can centralise the notion of checking for a present driver, and enforce that fwspecs aren't allocated unless and until we know they will be usable. Also use this opportunity to modernise with some "new" helpers that arrived shortly after this code was first written; the generic fwnode_handle_get() clears up that ugly get/put mismatch, while of_fwnode_handle() can now abstract those open-coded dereferences.

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 reStructuredText 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.
