[PATCH 1/4] m68k: Sort out !CONFIG_MMU_SUN3 vs. CONFIG_HAS_DMA

From: Geert Uytterhoeven
Date: Fri Dec 28 2012 - 14:23:36 EST


In two places, we check !CONFIG_MMU_SUN3 while we should check
CONFIG_HAS_DMA instead.
While fixing this, the check in <asm/dma-mapping.h> became redundant
(<linux/dma-mapping.h> already handles this case), so just remove it.
