Use the newly added of_reserved_mem_region_to_resource() and of_reserved_mem_region_count() functions to handle "memory-region" properties. The error handling is a bit different in some cases. Often "memory-region" is optional, so failed lookup is not an error. But then an error in of_reserved_mem_lookup() is treated as an error. However, that distinction is not really important. Either the region is available and usable or it is not. So now, it is just of_reserved_mem_region_to_resource() which is checked for an error.

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.
