But my point is that the struct device may be created dynamically at some point in time. This is how mmc/sd/sdio cards are handled. We don't have the information about the card and thus not the struct device of it, until we have detected it. Maybe we could at that point try to add the device to its PM domain? > >> Now, I haven't yet seen a demand for such a cases, but it seems wrong >> to not consider them.

How would that be solved?
