Subject: [PATCH v2 1/6] hw/i386/x86: Let ioapic_init_gsi() take parent as pointer
Date: Sat, 24 Feb 2024 14:58:46 +0100	[thread overview]
Message-ID: <20240224135851.100361-2-shentey@gmail.com> (raw)
In-Reply-To: <20240224135851.100361-1-shentey@gmail.com>

Rather than taking a QOM name which has to be resolved, let's pass the parent
directly as pointer. This simplifies the code.
