Stop calling bus_set_iommu() since it's now unnecessary. This also

the driver, which no longer needs to happen early either, so convert

The comment which starts here did not make it to the patch but it should have as it mentions bus_set_iommu() which is gone by the end of the series.

Heh, busted! In fact I think the whole point of that comment stops being true, but I couldn't be bothered to reason about it since one of the next steps after this is to start ripping all the arm_iommu_* stuff out anyway.

More general question/request - could you please include the exact sha1 the patchset is based on? It did not apply to any current trees and while it was trivial, it was slightly annoying to resolve the conflicts :)  Thanks,

v3 is based directly on 5.19-rc3:


And if it helps I have it on a branch here as well:
