[PATCH v2] ethernet: qualcomm: QCOM_EMAC should depend on HAS_DMA and HAS_IOMEM

From: Geert Uytterhoeven
Date: Thu Oct 06 2016 - 10:45:14 EST

If NO_DMA=y:

drivers/built-in.o: In function `emac_probe':
emac.c:(.text+0x3780b8): undefined reference to `bad_dma_ops'
emac.c:(.text+0x3780e2): undefined reference to `bad_dma_ops'
emac.c:(.text+0x378112): undefined reference to `bad_dma_ops'
emac.c:(.text+0x378146): undefined reference to `bad_dma_ops'
emac.c:(.text+0x37816e): undefined reference to `bad_dma_ops'
drivers/built-in.o:emac.c:(.text+0x37819a): more undefined references to `bad_dma_ops' follow


drivers/net/ethernet/qualcomm/emac/emac.c: In function âemac_removeâ:
drivers/net/ethernet/qualcomm/emac/emac.c:736:3: error: implicit declaration of function âiounmapâ [-Werror=implicit-function-declaration]

Add dependencies on HAS_DMA and HAS_IOMEM to fix this.

- Add dependency on HAS_IOMEM for UML.
