From 45e9504f109b84986ba9d25a273a5d5bd3f3e9d9 Mon Sep 17 00:00:00 2001 From: Zenghui Yu Date: Thu, 16 Jul 2020 16:39:05 +0800 Subject: genirq/irqdomain: Remove redundant NULL pointer check on fwnode The is_fwnode_irqchip() helper will check if the fwnode_handle is empty. There is no need to perform a redundant check outside of it.
