From f6e45661f9be546811b62b2b01f32f4bf0c436c0 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Fri, 22 Jan 2016 18:34:22 -0800 Subject: dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc() Rename dma_*_writecombine() to dma_*_wc(), so that the naming is coherent across the various write-combining APIs. Keep the old names for compatibility for a while, these can be removed at a later time. A guard is left to enable backporting of the rename, and later remove of the old mapping defines seemlessly. Build tested successfully with allmodconfig. The following Coccinelle SmPL patch was used for this simple transformation: @ rename_dma_alloc_writecombine @ expression dev, size, dma_addr, gfp; @@ -dma_alloc_writecombine(dev, size, dma_addr, gfp) +dma_alloc_wc(dev, size, dma_addr, gfp) @ rename_dma_free_writecombine @ expression dev, size, cpu_addr, dma_addr; @@ -dma_free_writecombine(dev, size, cpu_addr, dma_addr) +dma_free_wc(dev, size, cpu_addr, dma_addr) @ rename_dma_mmap_writecombine @ expression dev, vma, cpu_addr, dma_addr, size; @@ -dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size) +dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size) We also keep the old names as compatibility helpers, and guard against their definition to make backporting easier.
