To prevent its redundant implementation and streamline code, use memdup_user. This fixes warnings reported by Coccinelle: ./drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c:2811:13-20: WARNING opportunity for memdup_user Signed-off-by: Atul Raut <rauji.raut@xxxxxxxxx> --- drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c b/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c index 2df153828ff4..51740e007e89 100644 --- a/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c +++ b/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c @@ -2808,12 +2808,9 @@ static uint32_t *get_queue_ids(uint32_t num_queues, uint32_t *usr_queue_id_array if (!usr_queue_id_array) return NULL; - queue_ids = kzalloc(array_size, GFP_KERNEL); - if (!queue_ids) - return ERR_PTR(-ENOMEM); - - if (copy_from_user(queue_ids, usr_queue_id_array, array_size)) - return ERR_PTR(-EFAULT); + queue_ids = memdup_user(usr_queue_id_array, array_size); + if (IS_ERR(Iqueue_ids)) + return ERR_PTR(queue_ids); return queue_ids; } -- 2.34.1
