Re: [PATCH 09/11] [POWERPC] iSeries: move detection of virtual tapes

+#if defined(CONFIG_VIOTAPE) || defined(CONFIG_VIOTAPE_MODULE)
+/* Handle interrupt events for tape */
+static void __init handle_tape_event(struct HvLpEvent *event)
+{
+	struct vio_waitevent *we;
+	struct viotapelpevent *tevent = (struct viotapelpevent *)event;

I think we should generate these device tree entires unconditionally.
They're just a conversion of what the iseries firmware/hypervisor
provides and not dependent on a specific driver.

(dito for the other patches with the same scheme)
