From 528ad521a433cf873724893bda339df95d8ac1e0 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 11 Jun 2026 14:03:45 +0200 Subject: [PATCH] pmdomain: core: fix unused variable warning with !PM_GENERIC_DOMAINS_OF The genpd provider bus is really only used when CONFIG_PM_GENERIC_DOMAINS_OF is enabled, and since the recent deferred initialisation of domain parent devices, the root device pointer is otherwise unused. Fix the unused variable warning by moving the definition of the root device pointer inside the corresponding ifdef.
