Hi Vinod,
Today's linux-next merge of the slave-dma tree got conflicts in
arch/arm/include/asm/hardware/pl330.h and arch/arm/common/pl330.c between
commits 4272f98a1ae8 ("ARM: 7164/3: PL330: Fix the size of the
dst_cache_ctrl field") and 46e33c606af8 ("ARM: 7326/2: PL330: fix null
pointer dereference in pl330_chan_ctrl()") from Linus' tree and commit
b7d861d93945 ("DMA: PL330: Merge PL330 driver into drivers/dma/") from
the slave-dma tree.
I removed the files and then applied changes from the patchs in Linus'
tree to drivers/dma/pl330.c.
