A timer still armed\nby then reads V3D registers through the NULL vc4->v3d pointer, and the\nlate callbacks run on the vc4_dev embedding them after it has been\nfreed.\n\nDrain them in vc4_v3d_unbind(): shut the timer down and cancel\nreset_work before the interrupt is taken down, because its\nvc4_irq_reset() re-enables it, then flush job_done_work so that\ncompletions queued at teardown still release their jobs.\n\nThis issue was found by an in-house static analysis tool."
