[PATCH] Staging: most: MOST and MOSTCORE should depend on HAS_DMA

From: Geert Uytterhoeven
Date: Tue Sep 01 2015 - 16:06:06 EST

If NO_DMA=y:

ERROR: "dma_free_coherent" [drivers/staging/most/mostcore/mostcore.ko] undefined!
ERROR: "dma_alloc_coherent" [drivers/staging/most/mostcore/mostcore.ko] undefined!

As all MOST sub drivers use DMA functionality, add a dependency on
HAS_DMA to MOSTCORE, and to MOST, which selects MOSTCORE.

Say Y here if you want to enable MOST support.
