The first patch fixes the capture-buffer queue path introduced by cbb9c0d50e47. The second patch fixes the start-streaming, stop-streaming and device-run paths introduced by 2092b3833487. On a runtime resume failure, the decoder must not continue accessing VPU registers. Since pm_runtime_resume_and_get() does not retain a runtime PM usage reference on failure, these paths must also avoid calling an unmatched pm_runtime_put_autosuspend(). Each callback now handles the failure according to its interface by returning or completing queued buffers, cleaning up the stop-streaming path without touching hardware, or finishing the current mem2mem job. v2: - Check all four pm_runtime_resume_and_get() call sites in wave5-vpu-dec.c, as suggested by Nicolas. - Split the changes into two patches according to the commits that introduced the affected calls. - Add callback-specific cleanup for runtime resume failures.
