[PATCH 1/4] phy: cadence-torrent: Constify struct cdns_reg_pairs
From: Christophe JAILLET
Date: Thu Jul 11 2024 - 13:32:05 EST
'struct cdns_reg_pairs' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig:
Before:
======
text data bss dec hex filename
78154 20222 16 98392 18058 drivers/phy/cadence/phy-cadence-torrent.o
After:
=====
text data bss dec hex filename
85130 13214 16 98360 18038 drivers/phy/cadence/phy-cadence-torrent.o
Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
---
Compile tested-only.
