From: Colin Ian King <colin.king@xxxxxxxxxxxxx> Currently pointer pdd is being dereferenced when assigning pointer dpm and then pdd is being null checked. Fix this by checking if pdd is null before the dereference of pdd occurs. Addresses-Coverity: ("Dereference before null check") Fixes: 522b89c63370 ("drm/amdkfd: Track SDMA utilization per process") Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx> --- drivers/gpu/drm/amd/amdkfd/kfd_process.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_process.c b/drivers/gpu/drm/amd/amdkfd/kfd_process.c index 25636789f3d3..bdc58741b32e 100644 --- a/drivers/gpu/drm/amd/amdkfd/kfd_process.c +++ b/drivers/gpu/drm/amd/amdkfd/kfd_process.c @@ -103,10 +103,11 @@ static void kfd_sdma_activity_worker(struct work_struct *work) return; pdd = workarea->pdd; + if (!pdd) + return; dqm = pdd->dev->dqm; qpd = &pdd->qpd; - - if (!pdd || !dqm || !qpd) + if (!dqm || !qpd) return; mm = get_task_mm(pdd->process->lead_thread); -- 2.25.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
