[media] tc358743: only queue subdev notifications if devnode is set

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Hardware interrupts are enabled in the probe function, before the subdev
is registered to its v4l2_device. Until v4l2_device_register_subdev_node
is called, sd->devnode is NULL and v4l2_subdev_notify_event must not be
called.
