staging: ralink-gdma: fix kconfig dependency bug for DMA_RALINK
When DMA_RALINK is enabled and DMADEVICES is disabled, it results in the
following Kbuild warnings:
WARNING: unmet direct dependencies detected for DMA_ENGINE
Depends on [n]: DMADEVICES [=n]
Selected by [y]:
- DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n]
WARNING: unmet direct dependencies detected for DMA_VIRTUAL_CHANNELS
Depends on [n]: DMADEVICES [=n]
Selected by [y]:
- DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n]
The reason is that DMA_RALINK selects DMA_ENGINE and DMA_VIRTUAL_CHANNELS
without depending on or selecting DMADEVICES while DMA_ENGINE and
DMA_VIRTUAL_CHANNELS are subordinate to DMADEVICES. This can also fail
building the kernel as demonstrated in a bug report.
Honor the kconfig dependency to remove unmet direct dependency warnings
and avoid any potential build failures.
