From 3479c7ae9c1ddf04e720a2a9e6db046fee249745 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Tue, 9 Jul 2024 22:37:44 +0200 Subject: [PATCH] pinctrl: ti: ti-iodelay: Constify struct ti_iodelay_reg_data 'struct ti_iodelay_reg_data' is not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security.
