scsi: bnx2i: Use zeroing allocator rather than allocator/memset
Use dma_zalloc_coherent instead of dma_alloc_coherent followed by memset 0. Generated-by: scripts/coccinelle/api/alloc/kzalloc-simple.cocci Suggested-by: Luis R. Rodriguez <mcgrof@kernel.org> Signed-off-by: Himanshu Jha <himanshujha199640@gmail.com> Acked-by: Manish Rangankar <Manish.Rangankar@cavium.com> Signed-off-by: Martin K.
