[PATCH] peci: npcm: Constify struct peci_controller_ops​

From: Christophe JAILLET
Date: Sat Sep 07 2024 - 05:00:27 EST


'struct peci_controller_ops' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig:
Before:
======
text data bss dec hex filename
8003 784 48 8835 2283 drivers/peci/controller/peci-npcm.o

After:
=====
text data bss dec hex filename
8003 776 48 8827 227b drivers/peci/controller/peci-npcm.o
