In dma-contiguous.h, we try to access to dev->cma_area, so we need device.h. In the past, we included it luckily by swap.h in drivers/base/dma-contiguous.c. Swap.h includes node.h and then node.h includes device.h, so we were happy. But, in this patch, I remove 'include <linux/swap.h>' so we need to include device.h explicitly.
