Jonathan writes:

First found of IIO fixes for the 3.15 cycle.

* Fix the platform data support for the at91 adc driver.
* A couple of related follow up patches get the support working again
  for at91sam9260 and at91sam9g45 as the earlier patch results in a device
  name change.
* A default timer value in the at91 adc driver was bonkers.  Make it sane.
* Fix incorrect reporting of the integration time for the cm32181 light sensor
* Fix a missing break in the ad2s1200 driver which would have give a false
  error return.
* Make sure buffer scan mask queries from userspace return 0/1 rather than
  a fairly random value depending on their implementation of test_bit
* Fix leak of the i2c client and a null pointer dereference in the cm36651
  driver.
* Fix a build warning on avr32 for the mxs-lradc (not exactly a critical
  combination - but the issue was real).
