From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
Commit 5c0acf3b4f96 (driver core: Add comments about returning array
counts) forgot to update fwnode_property_read_string_array() along
the lines of device_property_read_string_array(), although it did
change the kerneldoc comment of it. Fix that.
