Reviewed-by: Robin Murphy <robin.mur...@arm.com> This seems like it could stand independently from the rest of the series - might be worth rewording the commit message to more general terms, i.e. arch_teardown_dma_ops() being the inverse of arch_setup_dma_ops() thus clearing the ops set by the latter, and sending it to Russell as a fix in its own right.
