History
Dafna Hirschfeld 6990570f7e media: v4l2-core: fix a use-after-free bug of sd->devnode 
sd->devnode is released after calling
v4l2_subdev_release. Therefore it should be set
to NULL so that the subdev won't hold a pointer
to a released object. This fixes a reference
after free bug in function
v4l2_device_unregister_subdev

Fixes: 0e43734d4c ("media: v4l2-subdev: add release() internal op")
