reset: rzg2l-usbphy-ctrl: Assign proper of node to the allocated device
[ Upstream commit 1f8af9712413f456849fdf3f3a782cbe099476d7 ]
The platform device named "rzg2l-usb-vbus-regulator", allocated by
the rzg2l-usbphy-ctrl driver, is used to instantiate a regulator driver.
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.
