Jonathan writes:

First round of IIO fixes for the 3.18 cycle.

* ad5933 - fix a null pointer dereference due to an old change that prevents
  different channels being registered for the buffer and used for sysfs
  interfaces.
* ad5933 - Drop a bonus _raw from attribute names.
* st-sensors - Makes sure the correct number of elements are copied when
  filling a local buffer copy.
* mxs-lradc - Disable clocks in a failure path during probe so they aren't
  left running.
