[Qemu-devel] [PULL 09/43] hw: set interrupts using pci irq wrappers


From: Michael S. Tsirkin
Subject: [Qemu-devel] [PULL 09/43] hw: set interrupts using pci irq wrappers
Date: Mon, 14 Oct 2013 17:58:21 +0300

From: Marcel Apfelbaum <address@hidden>

pci_set_irq and the other pci irq wrappers use
PCI_INTERRUPT_PIN config register to compute device
INTx pin to assert/deassert.

An irq is allocated using pci_allocate_irq wrapper
only if is needed by non pci devices.

Removed irq related fields from state if not used anymore.
