This commit http://git.kernel.org/cgit/linux/kernel/git/vkoul/slave-dma.git/commit/?h=next&id=8e66e7d682b04f7141f8ae666908c8dcd7fc0bfa
Renames xilinx_vdma_ prefix to xilinx_dma which includes renaming of the above properties.
The patch (dmaengine: vdma: Rename xilinx_vdma_ prefix to xilinx_dma) already got applied in the dma-next tree.
That's why sent this patch to sync with the current driver I mean latest driver.

Regards,
Kedar.
