Description
In the Linux kernel, the following vulnerability has been resolved:

drm/msm: Only fini scheduler after successful init

msm_ringbuffer_new() destroys a partially initialized ring through
msm_ringbuffer_destroy() when an allocation or scheduler setup step
fails.

If drm_sched_init() fails before it finishes initializing the scheduler,
the failure path still calls drm_sched_fini(). That teardown path assumes
the scheduler work items, lists, and workqueue state were initialized.

Track successful scheduler initialization and call drm_sched_fini() only
after drm_sched_init() returned 0.

This issue was found by a static analysis checker and confirmed by
manual source review.
