Log:
  make smbus_get_addr() an ivar accessor
  
  This is a direct commit to this branch.
  
  smbus_get_addr() was declared as a funciton prototype, but the function
  was never defined.  read_ivar and write_ivar methods were unused.
  
  This was exposed after jedec_ts driver was imported to this branch
  as that driver turned out to be the first user of smbus_get_addr().
  
  This change is a small subset of a larger change in r281985.
