dmaengine: consolidate tx_status functions2012-03-13T06:07:14ZRussell King - ARM Linuxlinux@arm.linux.org.uk2012-03-06T22:35:27Zurn:sha1:96a2af41c78b1fbb1f567a3486bdc63f7b31c5fd
Now that we have the completed cookie in the dma_chan structure, we
can consolidate the tx_status functions by providing a function to set
the txstate structure and returning the DMA status. We also provide
a separate helper to set the residue for cookies which are still in
progress.

Everyone deals with assigning DMA cookies in the same way (it's part of
the API so they should be), so lets consolidate the common code into a
helper function to avoid this duplication.

Add a local private header file to contain definitions and declarations
which should only be used by DMA engine drivers.
We also fix linux/dmaengine.h to use LINUX_DMAENGINE_H to guard against
multiple inclusion.
