From aa293583f0fe8b1634aeadbea06b4d0d04c30a95 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Mon, 16 Oct 2017 17:18:40 +0200 Subject: configfs: make ci_type field, some pointers and function arguments const The ci_type field of the config_item structure do not modify the fields of the config_item_type structure it points to. And the other pointers initialized with ci_type do not modify the fields as well. So, make the ci_type field and the pointers initialized with ci_type as const. Make the struct config_item_type *type function argument of functions config_{item/group}_init_type_name const as the argument in both the functions is only stored in the ci_type field of a config_item structure which is now made const. Make the argument of configfs_register_default_group const as it is only passed to the argument of the function config_group_init_type_name which is now const.
