serial: 8250: Only get RSA resource when required The probe for Remote Supervisor Adapter is limited to port i/o addresses which match one of the probe_rsa[] module parameter addresses. Limit RSA resource acquire to matching i/o ports. The result is a saner probe policy: only perform optional probes when specified rather than by default. NB: It is possible for userspace to set the port type == PORT_RSA with ioctl(TIOCSSERIAL) and then autoconfig with ioctl(TIOCSERCONFIG), which if it fails, may leave the port type set to PORT_RSA. Since this may have previously resulted in a working RSA port, this behavior is preserved.
