[PATCH] regulator: da9211: Constify struct regulator_desc

From: Christophe JAILLET
Date: Sun Sep 08 2024 - 04:50:43 EST


'struct regulator_desc' 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
13982 2118 16 16116 3ef4 drivers/regulator/da9211-regulator.o

After:
=====
text data bss dec hex filename
14622 1478 16 16116 3ef4 drivers/regulator/da9211-regulator.o
