[PATCH 2/2] hw/ipack: Remove legacy qemu_allocate_irqs() use


From: Philippe Mathieu-Daudé
Subject: [PATCH 2/2] hw/ipack: Remove legacy qemu_allocate_irqs() use
Date: Tue, 21 Jan 2025 08:44:12 +0100

No need to dynamically allocate IRQ when we know before hands
how many we'll use. Declare the 2 of them in IPackDevice state
and initialize them in the DeviceRealize handler.
