Hi Vinod, After merging the slave-dma tree, today's linux-next build (arm multi_v7_defconfig) produced this warning:
In file included from drivers/dma/xilinx/xilinx_vdma.c:26:0:

Presumable caused by the include order change in commit 937abe88aea3
("dmaengine: xilinx-dma: move header file to common location").
I guess that dmapool.h needs a "struct device;" line near the top.
