      AHCI: Cleanup checking of multiple MSIs/SLM modes · c3ebd6a9
      由 Alexander Gordeev 提交于 
      Sharing Last Message (SLM) mode is currently checked in two
functions: ahci_host_activate() and ahci_init_interrupts().
This update consolidates SLM mode check with activation of
multiple MSIs mode.

      libata-sff: Fix controllers with no ctl port · 6d8ca28f
      由 Ondrej Zary 提交于 
      Currently, ata_sff_softreset is skipped for controllers with no ctl port.
But that also skips ata_sff_dev_classify required for device detection.
This means that libata is currently broken on controllers with no ctl port.

So don't skip ata_sff_softreset, just skip the reset part of ata_bus_softreset
if the ctl port is not available.

This makes IDE port on ES968 behave correctly:
