From c94645b1b153e4e46599de0181cd517cd6d207d9 Mon Sep 17 00:00:00 2001 From: simran singhal Date: Wed, 29 Mar 2017 01:45:28 +0530 Subject: iio: adc: max1363: constify attribute_group structures Check for attribute_group structures that are only stored in the event_attrs filed of iio_info structure. As the event_attrs field of iio_info structures is constant, so these attribute_group structures can also be declared constant.
