But this driver overwrites subdev->flags immediately after calling v4l2_i2c_subdev_init(). So V4L2_SUBDEV_FL_IS_I2C is not set after all. This stops breaking subdev->flags and preserves V4L2_SUBDEV_FL_IS_I2C. Side note: According to the comment in v4l2_device_unregister(), this is problematic only if the device is platform bus device. Device tree or ACPI based devices are not affected.
