#1531682 — [PATCH] iio: 104-quad-8: Fix index control configuration

The LS7266R1 requires bits 5 & 6 to be high in order to select the Index
Control Register. This patch fixes a typo that incorrectly selects the
Input/Output Control Register where the Index Control Register was
desired.

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

Applied to the fixes-togreg-post-rc1 branch and marked for stable
(though that is probably irrelevant given this didn't apply to my fixes-togreg tree.
