[PATCH 3.16.y-ckt 02/71] iio: adis16400: Use != channel indices for the two voltage channels

From: Luis Henriques
Date: Thu Jun 25 2015 - 06:23:37 EST


3.16.7-ckt14 -stable review patch. If anyone has any objections, please let me know.

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

From: Paul Cercueil <paul.cercueil@xxxxxxxxxx>

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.
