I think such tricks are not supported neither in KMDF nor in WDM.

you can't get the senders PDEVICE_OBJECT, he may not even have one. Even if
you could, there is no guarantee the sender is WDF so there is
PDEVICE_OBJECT -> WDFDEVICE translation. Even if the sender was WDF, the
WDFDEVICE of the sender is private to the sender (for instance you cannot
get to the context).

why do you want to do this ?
