From d47552124bb0b9527da7a95357ae7d2e6046c4f6 Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Wed, 31 Jul 2024 13:12:49 -0600 Subject: [PATCH] PM / devfreq: imx-bus: Use of_property_present() Use of_property_present() to test for property presence rather than of_get_property(). This is part of a larger effort to remove callers of of_get_property() and similar functions. of_get_property() leaks the DT property data pointer which is a problem for dynamically allocated nodes which may be freed.
