Subject: [PATCH] genirq/irqdomain: Remove redundant NULL pointer check on fwnode
Date: Thu, 16 Jul 2020 16:39:05 +0800	[thread overview]
Message-ID: <20200716083905.287-1-yuzenghui@huawei.com> (raw)

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.
