The function, vhost_vdpa_alloc_domain(), has a pointer to a struct bus_type, but it should be constant as the function it passes it to expects it to be const, and the vhost code does not modify it in any way.

It will build and apply cleanly on top of 6.3-rc2 on its own, but I'd prefer if I could take it through my driver-core tree so that the driver core changes can be taken through there for 6.4-rc1. drivers/vhost/vdpa.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/vhost/vdpa.c b/drivers/vhost/vdpa.c index dc12dbd5b43b..08c7cb3399fc 100644 --- a/drivers/vhost/vdpa.c +++ b/drivers/vhost/vdpa.c @@ -1140,7 +1140,7 @@ static int vhost_vdpa_alloc_domain(struct vhost_vdpa *v) struct vdpa_device *vdpa = v->vdpa; const struct vdpa_config_ops *ops = vdpa->config; struct device *dma_dev = vdpa_get_dma_dev(vdpa); - struct bus_type *bus; + const struct bus_type *bus; int ret; /* Device want to do DMA by itself */ -- 2.39.2
