From db3b7e134185b27e6073618c1ad7eca1e4473eb4 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Mon, 16 Jan 2017 00:45:00 +0530 Subject: char: ipmi: constify ipmi_smi_handlers structures Declare ipmi_smi_handlers structures as const as they are only passed as an argument to the function ipmi_register_smi. This argument is of type const, so ipmi_smi_handlers structures having similar properties can be declared const too.
