[PATCH] rm pointless dmaengine exports
This removes several pointless exports from drivers/dma/dmaengine.c; the dma_async_memcpy_*() functions are inlined by <linux/dmaengine.h> so those exports are inappropriate. It also moves the existing EXPORT_SYMBOL declarations next to their functions, so it's now trivial to confirm one-to-one correspondence between exports and nonstatic symbols.
