power: supply: Propagate of_node to child device
Ensure that the dynamically created power supply device sets its
->of_node if the driver supplies one. This brings it in line with
several other subsystems (see git grep 'of_node =.*parent.*of_node') and
allows easier identification of the device from udev rules and similar.
Before this patch:
/sys/class/power_supply# ls -l bq256xx-battery/of_node
ls: cannot access 'bq256xx-battery/of_node': No such file or directory
# ls -l bq256xx-battery/hwmon1/of_node
ls: cannot access 'bq256xx-battery/hwmon1/of_node': No such file or directory
After:
/sys/class/power_supply# ls -l bq256xx-battery/of_node
