dmaengine: vdma: Use dma_pool_zalloc
Dma_pool_zalloc combines dma_pool_alloc and memset 0. The semantic patch that makes this transformation is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression d,e; statement S; @@ d = - dma_pool_alloc + dma_pool_zalloc (...); if (!d) S - memset(d, 0, sizeof(*d)); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Sören Brinkmann <soren.brinkmann@xilinx.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
