Subject[PATCH] device property: Check fwnode->secondary when finding properties
Date
fwnode_property_get_reference_args() searches for named properties
against a fwnode_handle, but these could instead be against the fwnode's
secondary. If the property isn't found against the primary, check the
secondary to see if it's there instead.
