[Nouveau] [PATCH] drm/nouveau/pmu: don't print reply values if exec is false
From: Colin Ian King <colin.king at canonical.com> Currently the uninitialized values in the array reply are printed out when exec is false and nvkm_pmu_send has not updated the array. Avoid confusion by only dumping out these values if they have been actually updated. Detected by CoverityScan, CID#1271291 ("Uninitialized scaler variable") Fixes: ebb58dc2ef8c ("drm/nouveau/pmu: rename from pwr (no binary change)") Signed-off-by: Colin Ian King <colin.king at canonical.com> --- drivers/gpu/drm/nouveau/nvkm/subdev/pmu/memx.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/nouveau/nvkm/subdev/pmu/memx.c b/drivers/gpu/drm/nouveau/nvkm/subdev/pmu/memx.c index 11b28b086a06..7b052879af72 100644 --- a/drivers/gpu/drm/nouveau/nvkm/subdev/pmu/memx.c +++ b/drivers/gpu/drm/nouveau/nvkm/subdev/pmu/memx.c @@ -88,10 +88,10 @@ nvkm_memx_fini(struct nvkm_memx **pmemx, bool exec) if (exec) { nvkm_pmu_send(pmu, reply, PROC_MEMX, MEMX_MSG_EXEC, memx->base, finish); + nvkm_debug(subdev, "Exec took %uns, PMU_IN %08x\n", + reply[0], reply[1]); } - nvkm_debug(subdev, "Exec took %uns, PMU_IN %08x\n", - reply[0], reply[1]); kfree(memx); return 0; } -- 2.19.1
