The variable `pm_suspend_target_state` is conditionally defined only when

referencing it without guarding by `#ifdef CONFIG_SUSPEND` causes build

a424353937c24554bb242a6582ed8f018b4a411c | Analyze and fix the following issue in the Linux kernel code: drm/xe/pf: Disable PF restart worker on device removal | Problem Details:
We can't let restart worker run once device is removed, since other
data that it might want to access could be already released.
Explicitly disable worker as part of device cleanup action.
Fixes: a4d1c5d0b99b ("drm/xe/pf: Move VFs reprovisioning to worker")

Avoid fd_install() until there are no more potential error paths, to
avoid put_unused_fd() after the fd is made visible to userspace.
