From 98b6d2b6764d75e386ce3236d771a7624a645e07 Mon Sep 17 00:00:00 2001 From: simran singhal Date: Fri, 31 Mar 2017 00:10:38 +0530 Subject: iio: light: lm3533-als: 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.
