From 0c0966b5019f97e2af0ab802c1453162748b1166 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 8 Sep 2024 10:41:11 +0200 Subject: [PATCH] regulator: da9211: Constify struct regulator_desc '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.
