Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6 

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6:
  ACPI: EC: Don't parse DSDT for EC early init on Compal
  ACPI: EC: Rewrite DMI checks
  ACPI: dock: fix "sibiling" typo
  ACPI: kill overly verbose "throttling states" log messages
  ACPI: Fix bound checks for copy_from_user in the acpi /proc code
  ACPI: fix bus scanning memory leaks
  ACPI: EC: Restart command even if no interrupts from EC
  sony-laptop: Don't unregister the SPIC driver if it wasn't registered
  sony-laptop: remove _INI call at init time
  sony-laptop: SPIC unset IRQF_SHARED, set IRQF_DISABLED
  sony-laptop: remove device_ctrl and the SPIC mini drivers
