   4 Subject: [PATCH] media: i2c: imx290: Add V4L2_SUBDEV_FL_HAS_EVENTS and
   5  subscribe hooks
   6
   7 Should be upstream commit 5f9dee39ab55
   8
   9 Any V4L2 subdevice that implements controls and declares
  10 V4L2_SUBDEV_FL_HAS_DEVNODE should also declare V4L2_SUBDEV_FL_HAS_EVENTS
  11 and implement subscribe_event and unsubscribe_event hooks.
  12
  13 This driver didn't and would therefore fail v4l2-compliance
  14 testing.
  15
  16 Add the relevant hooks.
