v4l2_i2c_subdev_init() sets the name of the sub-devices (as well as entities) to what is fairly certainly known to be unique in the system, even if there were more devices of the same kind. These drivers (m5mols, noon010pc30, ov9650, s5c73m3, s5k4ecgx, s5k6aa) set the name to the name of the driver or the module while omitting the device's I²C address and bus, leaving the devices with a static name and effectively limiting the number of such devices in a media device to 1. Address this by using the name set by the V4L2 framework.
