    First set of IIO fixes for the 3.16 cycle.
    A mixed bag of fixes, many of which feel just to late for 3.15.
    * hid sensors - some devices need a feature report request in order to
      change power state.  This isn't part of the spec, but has been observed
      on several devices and does no harm to others.
    * mpl3115 has had two errors in the buffer description fixed. The presure is
      signed, not unsigned and the temperature has 12 bits rather than 16.
      These could lead to incorrect interpretation of the data in userspace.
    * tsl2x7x - the high byte of the proximity thresholds should be written along
      with the low byte (which was). This could lead to interesting results
      with large thresholds.
    * twl4030 - a flag to specify processed values were required was not set
      when initializing a reading.  As such values returned were in an unknown
      state. Fixed by simply initializing it appropriately.
    * IIO_SIMPLE_DUMMY_BUFFER did not select IIO_BUFFER leading to randconfig
      build errors.
    * ak8975 was applying an unwanted le16_to_cpu conversion as the i2c framework
      already performs one.  As such for big endian systems, the bytes would be
      in the wrong order in the magnetic field measurements reported.
    * mxs-lradc - the controllable voltage dividers were not enabled / disabled for
      later channels than the first one during conversion.
    * at91_adc error handling returned -ENOMEM in a u8. Return value of
      at91_adc_get_trigger_value_by_name changed to int thus allowing -ENOMEM and
      also original values to be returned.
    * mcb - mcb_request_mem returns and ERR_PTR but the caller was checking for
      NULL to detect an error.
