Conditional registration is a problem for other subsystems which may

typical system already reveals plenty of entries from enabled but
otherwise irrelevant configs, so lets keep things simple and register
our context bus unconditionally too.

Applied, thanks.

Do we need this in v5.19 or is it enough if this gets into v5.20?

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.
