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. This bug was reported by TAXI in bko#14075. http://bugzilla.kernel.org/show_bug.cgi?id=14075Signed-off-by:
