[PATCH v5 10/11] dma: rename dma_*_writecombine() to dma_*_wc()

From: Luis R. Rodriguez
Date: Tue Aug 25 2015 - 11:53:53 EST

From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>

Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs.

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)
