Subject[PATCH 1/2] crypto: ccp - Include DMA declarations explicitly
From: Bjorn Helgaas <>

ccp-dev.h uses dma_direction, which is defined in linux/dma-direction.h.
Include that explicitly instead of relying on it being included via
linux/pci.h, since ccp-dev.h requires nothing else from linux/pci.h.

Similarly, ccp-dmaengine.c uses dma_get_mask(), which is defined in
linux/dma-mapping.h, so include that explicitly since it requires nothing
else from linux/pci.h.

A future patch will remove the includes of linux/pci.h where it is not
