From f7578496a671a96e501f16a5104893275e32c33a Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 18 Sep 2013 15:24:44 +0200 Subject: of/irq: Use irq_of_parse_and_map() Replace some instances of of_irq_map_one()/irq_create_of_mapping() and of_irq_to_resource() by the simpler equivalent irq_of_parse_and_map().
