These are fairly rare, but exist so we should wire it up. For 5.4 I plan to move the initilization to the common dma-remap code so it won't be missed for other architectures. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
