From 37f1c012f0f23b52df3a0d7850212b336fc9e595 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Fri, 10 Oct 2008 21:33:12 +0200 Subject: [PATCH] [S390] Use s390_root_dev_* in kvm_virtio. No need to define a static device for the kvm_s390 root device, just use s390_root_dev_register(). This is needed for the bus_id rework Acked-by: Carsten Otte Cc: Kay Sievers Signed-off-by: Cornelia Huck Signed-off-by: Greg Kroah-Hartman Signed-off-by: Martin Schwidefsky --- drivers/s390/kvm/kvm_virtio.c | 15 +++++++-------- 1 file changed, 7 insertions(+), 8 deletions(-) diff --git a/drivers/s390/kvm/kvm_virtio.c b/drivers/s390/kvm/kvm_virtio.c index 292b60da6dc7..ff4a6931bb8e 100644 --- a/drivers/s390/kvm/kvm_virtio.c +++ b/drivers/s390/kvm/kvm_virtio.c @@ -24,6 +24,7 @@ #include #include #include +#include #define VIRTIO_SUBCODE_64 0x0D00 @@ -241,10 +242,7 @@ static struct virtio_config_ops kvm_vq_configspace_ops = { * The root device for the kvm virtio devices. * This makes them appear as /sys/devices/kvm_s390/0,1,2 not /sys/devices/0,1,2. */ -static struct device kvm_root = { - .parent = NULL, - .bus_id = "kvm_s390", -}; +static struct device *kvm_root; /* * adds a new device and register it with virtio @@ -261,7 +259,7 @@ static void add_kvm_device(struct kvm_device_desc *d, unsigned int offset) return; } - kdev->vdev.dev.parent = &kvm_root; + kdev->vdev.dev.parent = kvm_root; kdev->vdev.id.device = d->type; kdev->vdev.config = &kvm_vq_configspace_ops; kdev->desc = d; @@ -317,15 +315,16 @@ static int __init kvm_devices_init(void) if (!MACHINE_IS_KVM) return -ENODEV; - rc = device_register(&kvm_root); - if (rc) { + kvm_root = s390_root_dev_register("kvm_s390"); + if (IS_ERR(kvm_root)) { + rc = PTR_ERR(kvm_root); printk(KERN_ERR "Could not register kvm_s390 root device"); return rc; } rc = vmem_add_mapping(PFN_PHYS(max_pfn), PAGE_SIZE); if (rc) { - device_unregister(&kvm_root); + s390_root_dev_unregister(kvm_root); return rc; }
