NAME
       dma_alloc_from_coherent - try to allocate memory from the per-device
       coherent area

SYNOPSIS
       int dma_alloc_from_coherent(struct device * dev, ssize_t size,
				   dma_addr_t * dma_handle, void ** ret);

ARGUMENTS
       dev
	   device from which we allocate memory

       size
	   size of requested memory area

       dma_handle
	   This will be filled with the correct dma handle

       ret
	   This pointer will be filled with the virtual address to allocated
	   area.

DESCRIPTION
       This function should be only called from per-arch dma_alloc_coherent to
       support allocation from per-device coherent memory pools.

       Returns 0 if dma_alloc_coherent should continue with allocating from
       generic memory areas, or !0 if dma_alloc_coherent should return ret.
