## Commit message ##
iio: adc: rockchip_saradc: fix information leak in triggered buffer
+ commit 38724591364e1e3b278b4053f102b49ea06ee17c upstream.
+
The 'data' local struct is used to push data to user space from a
triggered buffer, but it does not set values for inactive channels, as
it only uses iio_for_each_active_channel() to assign new values.
