* Updating libata to directly bind with ACPI / runtime power mgmt.
   This is a pre-req for SATA ZPODD (CD-ROM power management).
 
   Touches ACPI (exports++) and SCSI in minor ways.  Has been in linux-next
   for weeks.
 
   The rest of this should come via SCSI tree, as it involves a lot of updates
   to the 'sr' driver etc.
 
 Other, minor changes:
 
 * module_pci_driver() removes a lot of common boilerplate from each PCI driver
 
 * minor coding style, whitespace cleanups
 
 * pata_pcmcia bug fix, caught by Coccinelle
 
 * pata_imx, sata_dwc_460ex minor vendor updates
 
 * ahci_platform: use simple PM ops, and thereby add hibernation cb's
 
 * Add a few device-specific quirks
