Philipp Stanner 87210234e5 drm/sched: memset() 'job' in drm_sched_job_init() [ Upstream commit `2320c9e6a7` ] drm_sched_job_init() has no control over how users allocate struct drm_sched_job. Unfortunately, the function can also not set some struct members such as job->sched. This could theoretically lead to UB by users dereferencing the struct's pointer members too early. It is easier to debug such issues if these pointers are initialized to NULL, so dereferencing them causes a NULL pointer exception. Accordingly, drm_sched_entity_init() does precisely that and initializes its struct with memset(). Initialize parameter "job" to 0 in drm_sched_job_init().
