Merge branch 'for-3.17-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata fixes from Tejun Heo:
 "Two patches are to add PCI IDs for ICH9 and all others are device
  specific fixes.  Nothing too interesting"

* 'for-3.17-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  ahci_xgene: Fix the link down in first attempt for the APM X-Gene SoC AHCI SATA host controller driver.
  ahci_xgene: Skip the PHY and clock initialization if already configured by the firmware.
  ahci: add pcid for Marvel 0x9182 controller
  ata: Disabling the async PM for JMicron chip 363/361
  ata_piix: Add Device IDs for Intel 9 Series PCH
  ahci: Add Device IDs for Intel 9 Series PCH
  ata: ahci_tegra: Read calibration fuse
