Subject: [PATCH v2 0/2] media: i2c: Drop HAS_EVENTS and event handlers

Hi All,

After the introduction of [1] v4l2_subdev_init_finalize()
sets the HAS_EVENTS flag if a control handler is set, and
subdev_do_ioctl() uses v4l2_ctrl_subdev_subscribe_event()
and v4l2_event_subdev_unsubscribe() as defaults if the subdev
doesn't have .(un)subscribe.
Then Let's drop the HAS_EVENTS flag and event handlers.

As suggested by LPinchart imx415 imx415 sets the HAS_EVENTS
flags but not the event operations, all is already done from
[1] then we can drop the HAS_EVENTS.
