linux-next: build warning after merge of the slave-dma tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Vinod,

After merging the slave-dma tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/dma/xilinx/xilinx_vdma.c: In function 'xilinx_dma_prep_dma_cyclic':
drivers/dma/xilinx/xilinx_vdma.c:1808:23: warning: 'segment' may be used uninitialized in this function [-Wmaybe-uninitialized]
   segment->hw.control |= XILINX_DMA_BD_SOP;

Introduced by commit

  92d794dfb699 ("dmaengine: vdma: Add support for cyclic dma mode")

I am not sure if this is tecnically a problem, but gcc certainly cannot
tell.
