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: sleep: another HP/Compaq DMI entries for init_set_sci_en_on_resume
  ACPI: add DMI entry for SCI_EN resume quirk on HP dv4
  thermal: sysfs-api.txt - document passive attribute for thermal zones
  thermal: sysfs-api.txt - reformat for improved readability
  acpi: thermal: Add EOL to the trip_point_N_type strings
  ACPI: Move dereference after NULL test
  ACPICA: avoid "Info: mapping multiple BARs. Your kernel is fine."
  ACPI: add __cpuinit to acpi_processor_add()
  acpi-power-meter: Don't leak ACPI error codes to userspace
  eeepc-laptop: don't enable camera at startup if it's already on.
  Revert "eeepc-laptop: Prevent a panic when disabling RT2860 wireless when associated"
  ACPI: clean up video.c boundary checks and types
