From 3e4d6f91cae689b01865aedb71c1ad88a118084f Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 11 Sep 2017 12:42:31 +0100 Subject: [PATCH] RDMA/cxgb3: remove redundant first assignement of sqp sqp is being initialised when it is being declared and then updated a little later on making the first initialization redundant. Clean this up by initializing ptr and sqp at their declaration. Cleans up warning: "warning: Value stored to 'sqp' during its initialization is never read" Fixes: a58e58fafdff ("RDMA/cxgb3: Wrap the software send queue pointer as needed on flush") Signed-off-by: Colin Ian King Acked-by: Steve Wise Signed-off-by: Doug Ledford --- drivers/infiniband/hw/cxgb3/cxio_hal.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/drivers/infiniband/hw/cxgb3/cxio_hal.c b/drivers/infiniband/hw/cxgb3/cxio_hal.c index 3eff6541bd6f..3328acc53c2a 100644 --- a/drivers/infiniband/hw/cxgb3/cxio_hal.c +++ b/drivers/infiniband/hw/cxgb3/cxio_hal.c @@ -404,12 +404,10 @@ static void insert_sq_cqe(struct t3_wq *wq, struct t3_cq *cq, int cxio_flush_sq(struct t3_wq *wq, struct t3_cq *cq, int count) { - __u32 ptr; + __u32 ptr = wq->sq_rptr + count; int flushed = 0; - struct t3_swsq *sqp = wq->sq + Q_PTR2IDX(wq->sq_rptr, wq->sq_size_log2); + struct t3_swsq *sqp = wq->sq + Q_PTR2IDX(ptr, wq->sq_size_log2); - ptr = wq->sq_rptr + count; - sqp = wq->sq + Q_PTR2IDX(ptr, wq->sq_size_log2); while (ptr != wq->sq_wptr) { sqp->signaled = 0; insert_sq_cqe(wq, cq, sqp); -- 2.45.2
