The patch titled
Subject: dma-mapping: rename dma_*_writecombine() to dma_*_wc()
has been removed from the -mm tree. Its filename was
dma-rename-dma__writecombine-to-dma__wc.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: "Luis R. Rodriguez" <mcgrof@suse.com>
Subject: dma-mapping: 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 @
