[PULL 39/41] usb/uhci: Replace pci_set_irq with qemu_set_irq


From: Philippe Mathieu-Daudé
Subject: [PULL 39/41] usb/uhci: Replace pci_set_irq with qemu_set_irq
Date: Tue, 2 Nov 2021 14:42:38 +0100

From: BALATON Zoltan <balaton@eik.bme.hu>

Instead of using pci_set_irq, store the irq in the device state and
use it explicitly so variants having different interrupt handling can
use their own.
