The dmabounce dma_sync_xxx() implementation have been broken for quite some time; they all copy data between the DMA buffer and the CPU visible buffer no irrespective of the change of ownership. (IOW, a DMA_FROM_DEVICE mapping copies data from the DMA buffer to the CPU buffer during a call to dma_sync_single_for_device().) Fix it by getting rid of sync_single(), moving the contents into the recently created dmabounce_sync_for_xxx() functions and adjusting appropriately. This also makes it possible to properly support the DMA range sync functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> |
