It's hard to ensure cherry-picks have picked up all the dependencies correctly. If any of these really need to get cherry-picked into stable kernels, cc me and wait for my explicit Ack. Is there a pressing need for this in 4.19? -Saravana > --- > drivers/phy/tegra/xusb.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/phy/tegra/xusb.c b/drivers/phy/tegra/xusb.c > index dc22b1dd2c8ba..aa050aea2df58 100644 > --- a/drivers/phy/tegra/xusb.c > +++ b/drivers/phy/tegra/xusb.c > @@ -537,7 +537,7 @@ static int tegra_xusb_port_init(struct tegra_xusb_port *port, > > device_initialize(&port->dev); > port->dev.type = &tegra_xusb_port_type; > - port->dev.of_node = of_node_get(np); > + device_set_node(&port->dev, of_fwnode_handle(of_node_get(np))); > port->dev.parent = padctl->dev; > > err = dev_set_name(&port->dev, "%s-%u", name, index); > -- > 2.43.0 >
