Jonathan writes:

First set of IIO fixes in the 4.12 cycle.

Matt finally set up the lightning storm he needed to test the as3935.

* core
  - Fix a null pointer deference in iio_trigger_write_current when changing
  from a non existent trigger to another non existent trigger.
* a3935
  - Recalibrate the RCO after resume.
  - Fix interrupt mask so that we actually get some interrupts.
  - Use iio_trigger_poll_chained as we aren't in interrupt context.
* am335x
  - Fix wrong allocation size provided for private data to iio_device_alloc.
* bcm_iproc
  - Swapped primary and secondary isr handlers.
* ltr501
  - Fix swapped als/ps register fields when enabling interrupts
* max9611
  - Wrong scale factor for the shunt_resistor attribute.
* sun4-gpadc
  - Module autoloading fixes by adding the device table declarations.
  - Fix parent device being used in devm functions.
