+From 5e69ff59f7e51ddfde0b31587beb9e40ea1c85bc Mon Sep 17 00:00:00 2001

+Date: Thu, 19 Dec 2013 09:30:56 -0300
+Subject: [PATCH 185/203] of/irq: simplify args to irq_create_of_mapping
+
+All the callers of irq_create_of_mapping() pass the contents of a struct
+of_phandle_args structure to the function. Since all the callers already
+have an of_phandle_args pointer, why not pass it directly to
+irq_create_of_mapping()?
