    sata_sis: convert to slave_link · 72fee382
    Tejun Heo authored
    During introduction of slave_link, sata_sis slipped through the crack
    and left with ad-hoc merged SCR access.  As SCR status was shared for
    both the master and slave devices, when only one of the device is
    online, libata EH would think both are online but would only get valid
    device signature for the actually present one, which in turn trigger
    the probing safety net mechanism and make EH retry causing large delay
    during boot.  This patch converts sata_sis to slave_link mechanism.
