Subject: [PATCH 11/28] cross-tree: phase out dma_zalloc_coherent()
|
||
|
|
|
||
|
|
We already need to zero out memory for dma_alloc_coherent(), as such
|
||
|
|
using dma_zalloc_coherent() is superflous. Phase it out.
|
||
|
|
|
||
|
|
This change was generated with the following Coccinelle SmPL patch:
|
||
|

|
|
@ replace_dma_zalloc_coherent @

|
|
expression dev, size, data, handle, flags;
