From 765e3d8a71bbc1f3400667d5cfcfd7b03382d587 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Fri, 16 Mar 2007 13:38:05 -0800 Subject: [PATCH] [PATCH] rm pointless dmaengine exports This removes several pointless exports from drivers/dma/dmaengine.c; the dma_async_memcpy_*() functions are inlined by 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.
