[ Upstream commit 8e3967a71e6fca9c871f98b9289b59c82b88b729 ]
The variable `pm_suspend_target_state` is conditionally defined only when `CONFIG_SUSPEND` is enabled (see `include/linux/suspend.h`). Directly referencing it without guarding by `#ifdef CONFIG_SUSPEND` causes build failures when suspend functionality is disabled (e.g., `CONFIG_SUSPEND=n`).
