From b8f7bbd1f4ecff6d6277b8c454f62bb0a1c6dbe4 Mon Sep 17 00:00:00 2001 From: Ulf Hansson ulf.hansson@linaro.org Date: Fri, 22 Nov 2024 14:42:02 +0100 Subject: [PATCH] pmdomain: core: Add missing put_device()

When removing a genpd we don't clean up the genpd->dev correctly. Let's add the missing put_device() in genpd_free_data() to fix this.
