First round of new IIO drivers and cleanups for the 3.8 cycle.

Here we have

* New driver ad5449 with the introduction of a new IIO return type
  to simplify power of 2 dividers (extremely common case).
* Some coccinelle warning fixing patches (dull but worthwhile as
  make for easier automated testing and cut down on false positives).
* Some trivial bits of formatting cleanup and spelling corrections.
* Use kcalloc in a few places for semantic reasons.
* Stop lis3l02dq driver (soon to be dropped I hope) using now non
  existent irq_to_gpio.
* Some dead code/unused variable removal
* Convert a few drivers to generic core provided functions instead
  of their own versions.

So all in all a nice new driver and a lot of worthy but dull cleanup.
