The entity->dependency can go away completely once we've called drm_sched_entity_add_dependency_cb() (if the cb is called before we get around to tracing). The tracepoint is more useful if we trace every dependency instead of just ones that get callbacks installed, anyway, so just do that. Fixes any easy-to-produce OOPS when tracing the scheduler on V3D with "perf record -a -e gpu_scheduler:.\* glxgears" and DEBUG_SLAB enabled.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
