You are right, but this behavior is incorrect since each controller has only one physical USB PHY. > Is it a problem that we can end up with both a generic and legacy PHY? > I thought this was expected behavior at probe, and the rest of the code will > just use > the generic one in priority. > > Do you want to make it so that only one (generic or legacy) PHY remains after > probe? > Yes, I just want only one valid, either ci->phy or ci->usb_phy, it makes sense.
