From 7ab89e1e235cef11d50070e8b7170864ee4b7097 Mon Sep 17 00:00:00 2001 From: simran singhal Date: Sat, 1 Apr 2017 14:09:55 +0530 Subject: iio: proximity: as3935: constify attribute_group structures Check for attribute_group structures that are only stored in the attrs filed of iio_info structure. As the attrs field of iio_info structures is constant, so these attribute_group structures can also be declared constant.
