From a14e7fdd43040a2a5da2cc979063b3c958015aa9 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 13 Feb 2023 11:42:55 +0100 Subject: x86/uv: Use irq_domain_create_hierarchy() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use the irq_domain_create_hierarchy() helper to create the hierarchical domain, which both serves as documentation and avoids poking at irqdomain internals.
