Merge tag 'iio-fixes-for-4.4a' of ssh://ra.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes:
First set of IIO fixes for the 4.4 cycle.
This set does not include those for issues introduced during the merge
window. Fixes of those will follow in a future series.
* ad5064
- Make sure the local i2c_write returns 0 on success rather than the
number of bytes transfered. Otherwise we report an error on all writes.
- Fix a shift for ad5629 and ad5669 which gives incorrect DAC output on
these parts.
* ad7793
- The product ID on the datasheet is wrong. Fix it in the driver.
* IIO_DUMMY_EVGEN
- select IRQ_WORK as a dependency.
* lpc32xx
- make sure clock is prepared before enabling.
* si7020
- data byte order was reversed. Fix it.
* vf610
- Internal temperature calculation was wrong if a different
reference voltage was used. Now use a linear interpolation
function to make it work over the full range.
- Fix a division by zero in the case of a device tree property
not being present (same issue two fixes).
* xilinx XADC
- VREFN scale was wrong - fix it.
