The v4l2_i2c_subdev_init() sets V4L2_SUBDEV_FL_IS_I2C flag in the
subdev->flags. 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.
