Subject[PATCH v2] ASoC: atmel: ATMEL drivers depend on HAS_DMA
Date
On a config (such as arch/sh/) which does not set HAS_DMA when MMU
is not set, several ATMEL ASoC drivers select symbols that cause
kconfig warnings. There is one "depends on HAS_DMA" here but several
more are needed to prevent kconfig warnings since 'select' does not
recognize any dependencies.

Fix the following kconfig warnings:
