This patch enables the iio_dev and iio_chan_spec are set to NULL. This may prevent the page fault problem because the pointer of iio_chan_spec is initialized as NULL. The iio_chan_spec is updated only in case that the IIO map has specific channel label. When the map has no ADC channel label, then the value of iio_chan_spec remains as invalid pointer. To prevent this problem, the pointer should be initialized as NULL. Signed-off-by: Milo(Woogyom) Kim Signed-off-by: Jonathan Cameron --- Reading git-diff-tree failed
