Lucas Stach a7fbb630c5 drm/scheduler: fix inconsistent locking of job_list_lock ... 1db8c142b6 (drm/scheduler: Add drm_sched_suspend/resume_timeout()) made the job_list_lock IRQ safe in as the suspend/resume calls were expected to be called from IRQ context. This usage never materialized in upstream. Instead amdgpu started locking the job_list_lock in an IRQ unsafe way in amdgpu_ib_preempt_mark_partial_job() and amdgpu_ib_preempt_job_recovery(), which leads to potential deadlock if one would actually start to call the drm_sched_suspend/resume_timeout functions from IRQ context. As no current user needs the locking to be IRQ safe, the local IRQ disable/enable is pure overhead. Fix the inconsistent locking by changing all uses of job_list_lock to use the IRQ unsafe locking primitives.
