Kernel series 3.11 and 3.12 does not initialize scan_index in the iio_chan_spec structure as 3.13 and newer does. This is necessary for the stepid patch to work, otherwise it even breaks the cases that worked before the stepid patch. Unfortunately the stepid patch seems to already be in 3.12.25, must have missed that inclusion.
