Or am I missing something? > 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. -- linux-i3c mailing list linux-i3c@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-i3c
