It's not strictly a critical fix, so I think 5.20 is fine. I plan to 
post v4 of my bus_set_iommu() series next week as the hopefully-final 
version, but at this point I think it might be safer to hold off 
actually merging that until early next cycle, to give it plenty of time 
in -next.

Thanks,
Robin.
