From: Oleksandr Andrushchenko <oleksandr_andrushchenko@xxxxxxxx> Dan Carpenter has reported that there is the following static checker warning: drivers/gpu/drm/drm_prime.c:317 drm_gem_map_dma_buf() warn: 'sgt' can also be NULL 314 sgt = obj->dev->driver->gem_prime_get_sg_table(obj); 315 316 if (!IS_ERR(sgt)) { 317 if (!dma_map_sg_attrs(attach->dev, sgt->sgl, sgt->nents, dir, And one of the problematic functions is xen_drm_front_gem_get_sg_table.
