From 75aba7b0e9ac416ca53c0c97680b8e9aedf09284 Mon Sep 17 00:00:00 2001 From: Suravee Suthikulpanit Date: Thu, 10 Dec 2015 08:55:28 -0800 Subject: irqdomain: Introduce is_fwnode_irqchip helper Since there will be several places checking if fwnode.type is equal FWNODE_IRQCHIP, this patch adds a convenient function for this purpose.
