From 03c3bdebaad23d6698a3cb8a11a915d8bdebf28f Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 26 Nov 2025 17:58:50 +0100 Subject: [PATCH] regulator: pca9450: Constify pointers to 'regulator_desc' wrap struct Pointer to 'struct regulator_desc' is a pointer to const and the wrapping structure (container) is not being modified, thus entire syntax can be replaced to preferred and safer container_of_const().
