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")
