Hi Hans, Do you know why I2C and SPI devices are unregistered in v4l2_device_unregister() but not in v4l2_device_unregister_subdev() ? If I call the later manually before calling v4l2_device_unregister(), the I2C and SPI devices won't be unregistered. Is that expected ? -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
