Subject: [PATCH v4 14/19] irqchip/gic-v2m: Use irq_domain_create_hierarchy()
Date: Mon, 16 Jan 2023 14:50:39 +0100 [thread overview]
Message-ID: <20230116135044.14998-15-johan+linaro@kernel.org> (raw)
In-Reply-To: <20230116135044.14998-1-johan+linaro@kernel.org>
Use the irq_domain_create_hierarchy() helper to create the hierarchical
domain, which both serves as documentation and avoids poking at
irqdomain internals.
