Necip Fazil Yildiran 4e1d17a1f7 sh: dma: fix kconfig dependency for G2_DMA
commit f477a538c14d07f8c45e554c8c5208d588514e98 upstream.

When G2_DMA is enabled and SH_DMA is disabled, it results in the following
Kbuild warning:

WARNING: unmet direct dependencies detected for SH_DMA_API
  Depends on [n]: SH_DMA [=n]
  Selected by [y]:
  - G2_DMA [=y] && SH_DREAMCAST [=y]

The reason is that G2_DMA selects SH_DMA_API without depending on or
selecting SH_DMA while SH_DMA_API depends on SH_DMA.

When G2_DMA was first introduced with commit 40f49e7ed7
("sh: dma: Make G2 DMA configurable."), this wasn't an issue since
SH_DMA_API didn't have such dependency, and this way was the only way to
enable it since SH_DMA_API was non-visible. However, later SH_DMA_API was
made visible and dependent on SH_DMA with commit d8902adcc1
("dmaengine: sh: Add Support SuperH DMA Engine driver").

Let G2_DMA depend on SH_DMA_API instead to avoid Kbuild issues.

Fixes: d8902adcc1 ("dmaengine: sh: Add Support SuperH DMA Engine driver")

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.
