From 0fa90023f23ced839cde3bcc0be4e06b3fc34895 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sun, 2 Oct 2016 00:45:13 +0530 Subject: [PATCH] Staging: iio: ad7816: 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.
