* 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev:
  pata_it821x: Driver updates and reworking
  libata.h: replace __FUNCTION__ with __func__
  ata_piix: subsys 106b:00a3 is apple ich8m too
  libata-core: make sure that ata_force_tbl is freed in case of an error
  libata: update atapi disable handling
  pata_via: add VX800 flag; add function for fixing h/w bugs
  pata_ali: misplaced pci_dev_put()
