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.
