Subject[PATCH 1/1] firmware: arm_scpi: add missing of_node_put after calling of_parse_phandle
Date
of_node_put needs to be called when the device node which is got
from of_parse_phandle has finished using.

Besides, of_address_to_resource always returns -EINVAL for error, delete
the assignment for ret.
