[PATCH 4/4] mtd: provide helper to prepare buffers for DMA operations
Some NAND controller drivers are making use of DMA to transfer data from the controller to the buffer passed by the MTD user. Provide a generic mtd_map/unmap_buf() implementation to avoid open coded (and sometime erroneous) implementations. Signed-off-by: Boris Brezillon
