Merge tag 'iio-fixes-for-4.3a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes:
First set of IIO fixes for the 4.3 cycle.
* twl4030 - incorrect readings for some channels due to a failure to
initialize a bias regulator or configure the lines for input rather than
USB use.
* lis3lv02 - a missunderstanding of the way the interrupts worked on this
chip lead to activation of the wrong interrupt.
* sca3000 - an old bug meant that memory corruption could occur in the
hardware ring buffer readout function.
* mxs-lradc - wrong temp offset.
