The patch caused the problem.
You moved v4l2_device_register() from saa7146_vv_init() to
saa7146_vv_devinit(), but you did not modify av7110_v4l.c and
budget-av.c accordingly.
$ grep saa7146_vv_init v4l/*c
v4l/av7110_v4l.c: ret = saa7146_vv_init(dev, vv_data);
v4l/budget-av.c: if (0 != saa7146_vv_init(dev, &vv_data)) {
v4l/hexium_gemini.c: saa7146_vv_init(dev, &vv_data);
v4l/hexium_orion.c: saa7146_vv_init(dev, &vv_data);
v4l/mxb.c: saa7146_vv_init(dev, &vv_data);
v4l/saa7146_fops.c:int saa7146_vv_init(struct saa7146_dev* dev, struct saa7146_ext_vv *ext_vv)
v4l/saa7146_fops.c:EXPORT_SYMBOL_GPL(saa7146_vv_init);
v4l/saa7146_fops.c:static int __init saa7146_vv_init_module(void)
v4l/saa7146_fops.c:module_init(saa7146_vv_init_module);
$ grep saa7146_vv_devinit v4l/*c
v4l/hexium_gemini.c: ret = saa7146_vv_devinit(dev);
v4l/hexium_orion.c: err = saa7146_vv_devinit(dev);
v4l/mxb.c: err = saa7146_vv_devinit(dev);
v4l/saa7146_fops.c:int saa7146_vv_devinit(struct saa7146_dev *dev)
v4l/saa7146_fops.c:EXPORT_SYMBOL_GPL(saa7146_vv_devinit);
