Make sure to drop the references taken to the vtg devices by of_find_device_by_node() when looking up their driver data during component probe.
Markus suggested “Prevent device leak in of_vtg_find()” as commit summary.
Markus has gotten himself banned from the mailing lists some years ago and even if he is now back with a new mail address most of us still ignore him.
I prefer the Subject as it stands since it captures when the leaks happens, but I don't mind mentioning of_vtg_find() instead if you insist.
Can this one be picked up for 6.19 or do you want me to respin?
Note that holding a reference to a platform device does not prevent its driver data from going away so there is no point in keeping the reference after the lookup helper returns.
