[PATCH 1/3] ata: sata_sil: Continue probing other sata port when failed current port.

[Peng Ma]

 In the initialization of sata driver, we want to initialize all port
 probes, Therefore, any detection failure between of them should continue
 initialization by skipping the current port instead of exit.
