From: bui duc phuc <[email protected]> devm_kasprintf() can fail when allocating the wakeup IRQ name. The error was logged with dev_err_probe(), but its return value was ignored and probe could continue with a successful return value. Store the error returned by dev_err_probe() in ret and jump to the error path to propagate the failure.
