This regulator driver is associated with a device tree (DT) node, which is a child of the rzg2l-usbphy-ctrl DT node. The regulator's DT node allows consumer nodes to reference the regulator and configure the regulator as needed. Starting with commit cd7a38c40b23 ("regulator: core: do not silently ignore provided init_data") the struct regulator_dev::dev::of_node is no longer populated using of_node_get(config->of_node) if the regulator does not provide init_data. Since the rzg2l-usb-vbus-regulator does not provide init_data, this behaviour causes the of_find_regulator_by_node() function to fails, resulting in errors when attempting to request the regulator. To fix this issue, call device_set_of_node_from_dev() for the "rzg2l-usb-vbus-regulator" platform device.
