The direction field in the DMA config is deprecated. The sh-sci driver
sets {src,dst}_{addr,addr_width} based on the DMA direction and
it results in dmaengine_slave_config() failure as RZ DMAC driver
validates {src,dst}_addr_width values independent of DMA direction.
Fix this issue by passing both {src,dst}_{addr,addr_width}
values independent of DMA direction.

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.
