6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Russell King (Oracle) <rmk+kernel@xxxxxxxxxxxxxxx> [ Upstream commit dd0c9855b41310470086500c9963bbb64bb90dd0 ] We convert from a phylink_config struct to a dsa_port struct in many places, let's provide a helper for this.
