+Subject: [PATCH 188/203] of/irq: Rework of_irq_count()
+
+The of_irq_to_resource() helper that is used to implement of_irq_count()
+tries to resolve interrupts and in fact creates a mapping for resolved
+interrupts. That's pretty heavy lifting for something that claims to
+just return the number of interrupts requested by a given device node.
+
+Instead, use the more lightweight of_irq_map_one(), which, despite the
+name, doesn't create an actual mapping. Perhaps a better name would be
+of_irq_translate_one().
