Yes, the latter case was in my mind that whoever runs this driver on 
earlier stable kernel and has enough devices on the bus where previous 
code will calculate wrong can request the backport or at least be vocal 
about it :-)

I'd say backporting back to 9ad9a52cce28 ("i3c/master: introduce the 
mipi-i3c-hci driver") is also needless because driver needs other fixes 
in order to be really usable.
