From 612a462acbb9f3bfc7c8433b44118b0a156560da Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Mon, 16 Oct 2017 17:18:43 +0200 Subject: iio: make function argument and some structures const Make the argument of the functions iio_sw{d/t}_group_init_type_name const as they are only passed to the function config_group_init_type_name having the argument as const. Make the config_item_type structures const as they are either passed to the functions having the argument as const or they are stored in the const "ci_type" field of a config_item structure.
