Right, notice I said "link it":
struct vfio_platform_irq *irq =
container_of(prod, struct vfio_platform_irq, producer);
struct vfio_platform_device *vpdev = irq->vpdev;
struct vfio_device *vdev = vpdev->vdev;
Would this be okay?

Right, notice I said "link it":
struct vfio_platform_irq *irq =
container_of(prod, struct vfio_platform_irq, producer);
struct vfio_platform_device *vpdev = irq->vpdev;
struct vfio_device *vdev = vpdev->vdev;
Would this be okay?
