Subject: iio: 104-quad-8: Fix off-by-one error when addressing flag register
From: William Breathitt Gray <vilhelm.gray@xxxxxxxxx>
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.
