We use delayed_work in HPD handling, and cancel any scheduled work in tfp410_fini using cancel_delayed_work_sync(). However, we have only initialized the delayed work if we actually have a HPD interrupt configured in the DT, but in the tfp410_fini, we always cancel the work, possibly causing a WARN(). Fix this by doing the cancel only if we actually had the delayed work set up.
