Subject: iio: 104-quad-8: Fix off-by-one error when addressing flag register

From: William Breathitt Gray <[email protected]>

commit ca8d8e03b4c9ad447d1e882cc8014e538f653018 upstream.

The flag register is offset by 1 from the respective channel data register. This patch fixes an off-by-one error when attempting to read a channel flag register where the base address was not properly offset.

Fixes 28e5d3bb0325 ("iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8")
