From 56fb37efcae9ead8077fe9657bbd1ae2d374ac50 Mon Sep 17 00:00:00 2001 From: Rikard Falkeborn Date: Sun, 7 Feb 2021 21:25:01 +0100 Subject: [PATCH] staging: fieldbus: arcx-anybus: constify static structs Constify two static structs which are never modified, to allow the compiler to put them in read-only memory. The only usage of controller_attribute_group is to put its address in an array of pointers to const struct attribute_group, and the only usage of can_power_ops is to assign its address to the 'ops' field in the regulator_desc struct, which is a pointer to const struct regulator_ops.
