This patch set includes two instances where the list iterator variable 'pstate' is implicitly assumed to be valid after the iterator loop. While in pratice that is most likely the case (if 'pstatei'/'args->v0.state' is <= the elements in clk->states), we should explicitly only allow 'pstate' to always point to correct 'nvkm_pstate' structs. That

Hi Ben, still _assuming_ it's an issue of the card I thought about why it works with the NVIDIA binary driver. And I can image they're just trying to do an identity-mapping first and if that doesn't work (e.g. the particular SOR is already in use by another macro link) they just pick the next suitable one. So the case would be that the NVIDIA binary driver always assignes the only
