Subject[PATCH 4.0 032/105] iio: adis16400: Use != channel indices for the two voltage channels
Date
4.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Paul Cercueil <paul.cercueil@analog.com>

commit 7323d59862802ca109451eeda9777024a7625509 upstream.

Previously, the two voltage channels had the same ID, which didn't cause
conflicts in sysfs only because one channel is named and the other isn't;
this is still violating the spec though, two indexed channels should never
have the same index.
