From 4214dc1807afa0a9eb84f845c9c2772dcbeae0f8 Mon Sep 17 00:00:00 2001 From: simran singhal Date: Sat, 1 Apr 2017 13:47:51 +0530 Subject: [PATCH] iio: adc: hx711: 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.
