mfd: sta2x11-mfd: Only add sta2x11_mfd if it hasn't already been added
The pci probe method is called twice now, so we have to call sta2x11_mfd_add() only once to avoid a -EBUSY error. Signed-off-by: Davide Ciminaghi <ciminaghi@gnudd.com> Acked-by: Alessandro Rubini <rubini@gnudd.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
