If dev is NULL, then you *must* setup v4l2_dev->name before calling v4l2_device_register. The first 'dev' argument is normally the struct device pointer of a pci_dev, -usb_device or platform_device. It is rare for dev to be NULL, but it happens +usb_interface or platform_device. It is rare for dev to be NULL, but it happens with ISA devices or when one device creates multiple PCI devices, thus making it impossible to associate v4l2_dev with a particular parent. diff --git a/linux/drivers/media/video/au0828/au0828-core.c b/linux/drivers/media/video/au0828/au0828-core.c index ffe1bf019..ab25af430 100644 --- a/linux/drivers/media/video/au0828/au0828-core.c +++ b/linux/drivers/media/video/au0828/au0828-core.c @@ -37,8 +37,6 @@ int au0828_debug; module_param_named(debug, au0828_debug, int, 0644); MODULE_PARM_DESC(debug, "enable debug messages"); -static atomic_t au0828_instance = ATOMIC_INIT(0); - #define _AU0828_BULKPIPE 0x03 #define _BULKPIPESIZE 0xffff @@ -170,7 +168,7 @@ static void au0828_usb_disconnect(struct usb_interface *interface) static int au0828_usb_probe(struct usb_interface *interface, const struct usb_device_id *id) { - int ifnum, retval, i; + int ifnum, retval; struct au0828_dev *dev; struct usb_device *usbdev = interface_to_usbdev(interface); @@ -198,10 +196,7 @@ static int au0828_usb_probe(struct usb_interface *interface, usb_set_intfdata(interface, dev); /* Create the v4l2_device */ - i = atomic_inc_return(&au0828_instance) - 1; - snprintf(dev->v4l2_dev.name, sizeof(dev->v4l2_dev.name), "%s-%03d", - "au0828", i); - retval = v4l2_device_register(&dev->usbdev->dev, &dev->v4l2_dev); + retval = v4l2_device_register(&interface->dev, &dev->v4l2_dev); if (retval) { printk(KERN_ERR "%s() v4l2_device_register failed\n", __func__); diff --git a/linux/drivers/media/video/cx231xx/cx231xx-cards.c b/linux/drivers/media/video/cx231xx/cx231xx-cards.c index d1872988a..245c49e9d 100644 --- a/linux/drivers/media/video/cx231xx/cx231xx-cards.c +++ b/linux/drivers/media/video/cx231xx/cx231xx-cards.c @@ -683,9 +683,7 @@ static int cx231xx_usb_probe(struct usb_interface *interface, */ /* Create v4l2 device */ - snprintf(dev->v4l2_dev.name, sizeof(dev->v4l2_dev.name), - "%s-%03d", "cx231xx", nr); - retval = v4l2_device_register(&udev->dev, &dev->v4l2_dev); + retval = v4l2_device_register(&interface->dev, &dev->v4l2_dev); if (retval) { cx231xx_errdev("v4l2_device_register failed\n"); cx231xx_devused &= ~(1 << nr); diff --git a/linux/drivers/media/video/pvrusb2/pvrusb2-hdw.c b/linux/drivers/media/video/pvrusb2/pvrusb2-hdw.c index def29ddb3..c1fd23e1f 100644 --- a/linux/drivers/media/video/pvrusb2/pvrusb2-hdw.c +++ b/linux/drivers/media/video/pvrusb2/pvrusb2-hdw.c @@ -2591,7 +2591,7 @@ struct pvr2_hdw *pvr2_hdw_create(struct usb_interface *intf, hdw->ctl_read_urb = usb_alloc_urb(0,GFP_KERNEL); if (!hdw->ctl_read_urb) goto fail; - if (v4l2_device_register(&usb_dev->dev, &hdw->v4l2_dev) != 0) { + if (v4l2_device_register(&intf->dev, &hdw->v4l2_dev) != 0) { pvr2_trace(PVR2_TRACE_ERROR_LEGS, "Error registering with v4l core, giving up"); goto fail; diff --git a/linux/drivers/media/video/usbvision/usbvision-video.c b/linux/drivers/media/video/usbvision/usbvision-video.c index fa62a2fd7..7db493ca8 100644 --- a/linux/drivers/media/video/usbvision/usbvision-video.c +++ b/linux/drivers/media/video/usbvision/usbvision-video.c @@ -1522,7 +1522,8 @@ static int __devinit usbvision_register_video(struct usb_usbvision *usbvision) * Returns NULL on error, a pointer to usb_usbvision else. * */ -static struct usb_usbvision *usbvision_alloc(struct usb_device *dev) +static struct usb_usbvision *usbvision_alloc(struct usb_device *dev, + struct usb_interface *intf) { struct usb_usbvision *usbvision; @@ -1531,7 +1532,7 @@ static struct usb_usbvision *usbvision_alloc(struct usb_device *dev) return NULL; usbvision->dev = dev; - if (v4l2_device_register(&dev->dev, &usbvision->v4l2_dev)) + if (v4l2_device_register(&intf->dev, &usbvision->v4l2_dev)) goto err_free; mutex_init(&usbvision->lock); /* available */ @@ -1669,7 +1670,8 @@ static int __devinit usbvision_probe(struct usb_interface *intf, return -ENODEV; } - if ((usbvision = usbvision_alloc(dev)) == NULL) { + usbvision = usbvision_alloc(dev, intf); + if (usbvision == NULL) { dev_err(&intf->dev, "%s: couldn't allocate USBVision struct\n", __func__); return -ENOMEM; } diff --git a/linux/drivers/media/video/w9968cf.c b/linux/drivers/media/video/w9968cf.c index cf8548a7f..63658bfd2 100644 --- a/linux/drivers/media/video/w9968cf.c +++ b/linux/drivers/media/video/w9968cf.c @@ -3454,7 +3454,7 @@ w9968cf_usb_probe(struct usb_interface* intf, const struct usb_device_id* id) if (!cam) return -ENOMEM; - err = v4l2_device_register(&udev->dev, &cam->v4l2_dev); + err = v4l2_device_register(&intf->dev, &cam->v4l2_dev); if (err) goto fail0; |
