[RFC v4 05/18] vb2: Anticipate queue specific DMA attributes for USERPTR buffers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The DMA attributes were available for the memop implementation for MMAP
buffers but not for USERPTR buffers. Do the same for USERPTR. This patch
makes no functional changes.
