  "6th set of IIO new driver support, clean up and fixes for the 3.8 cycle
   (possibly wait until 3.9 cycle given timing).

   Here we have
   * the cleanup and move out of staging of ad7793.
   * addition support for additional parts to ad7793.
   * a basic new driver for TI ADC081C021/027
   * 4 little fixes for the recent addition of ad16136 and ad16480.

   So some nice work with nothing controversial or anything that
   will effect stuff outside the drivers in question."
