From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> Now that the ACPI companions of devices are pointed to by the fwnode field in struct device, the device_property_*() accessor functions can be modified to use their fwnode_property_*() counterparts internally with minimum extra overhead in the IS_ENABLED(CONFIG_OF) case, so make those changes. This allows us to get rid of the rather ugly DEV_PROP_READ_ARRAY() macro among other things. Signed-off-by: Rafael J.
