Subject: [PATCH v6 17/20] irqchip/gic-v3-mbi: Use irq_domain_create_hierarchy()
Date: Mon, 13 Feb 2023 11:42:59 +0100 [thread overview]
Message-ID: <20230213104302.17307-18-johan+linaro@kernel.org> (raw)
In-Reply-To: <20230213104302.17307-1-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.
