Subject: [PATCH] net: ethernet: mtk_wed: No need to clear memory after a
|
|
dma_alloc_coherent() call
|
|
|
|
dma_alloc_coherent() already clears the allocated memory, there is no need
|
|
to explicitly call memset().
|
|
|
|
Moreover, it is likely that the size in the memset() is incorrect and
|
|
should be "size * sizeof(*ring->desc)".
