 - Fix for a regression causing a failure to turn on some devices on

   leaving everyone else alone.

 - ACPI power resources initialization fix preventing a NULL pointer
   from being dereferenced in the acpi_add_power_resource() error code
   path.

 - ACPI dock station driver fix that adds missing locking to
   write_undock().

 - ACPI resources allocation fix changing the scope of an old workaround
   so that it doesn't affect systems that aren't actually buggy.  This
   was reported a couple of days ago to fix DMA problems on some new
   platforms so we need it in -stable.  From Mika Westerberg.
