      dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc() · f6e45661

      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.
