Having of_reserved_mem_device_init() forcibly reconfigure DMA for all callers, potentially overriding the work done by a bus-specific .dma_configure method earlier, is at best a bad idea and at worst actively harmful. If drivers really need virtual devices to own dma-coherent memory, they should explicitly configure those devices based on the appropriate firmware node as they create them. It looks like the only driver not passing in a proper OF platform device is s5p-mfc, so move the rogue of_dma_configure() call into that driver where it logically belongs.

README
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.
