Subject: [PATCH v5 18/19] irqchip/mvebu-odmi: Use irq_domain_create_hierarchy()
Date: Thu, 9 Feb 2023 14:23:22 +0100 [thread overview]
Message-ID: <20230209132323.4599-19-johan+linaro@kernel.org> (raw)
In-Reply-To: <20230209132323.4599-1-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.
