[PATCH v2] media: i2c: imx219: Declare that the driver can create events

[Dafna Hirschfeld]

From: Dave Stevenson <dave.stevenson at raspberrypi.com>

The flag V4L2_SUBDEV_FL_HAS_EVENTS is required if the subdev can
generate events. It can create events from the ctrl handler, therefore
this is required.
