    dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc() · f6e45661
    Luis R. Rodriguez authored
    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
    @ 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.
