  xpp: Use proper get/set for device->driver_data
  
  2.6.32-rc1 broke direct access to the member 'driver_data' of 'struct
  device'. However direct access to wasn't proper in the first place.
  
  This commit replaces direct access to dev->driver_data with
  dev_get_drvdata() and dev_set_drvdata().

  dahdi-base: Include linux/sched.h
  
  Commit a99bba to the mainline kernel removed sched.h from poll.h. So
  dahdi-base.c needs to include sched.h directly now.
