5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Guangshuo Li [ Upstream commit b64f763b607426ac97e44b114f0b8844ac3b86dd ] cpsw_probe() registers devlink before registering the CPSW ports. If cpsw_register_ports() fails, the error path only unregisters the notifiers and then releases the lower level resources. It does not undo the successful cpsw_register_devlink() call, leaving the devlink instance and its parameters registered after probe has failed. Add a devlink cleanup label for the path where devlink registration has already succeeded, and use it when port registration fails.
