USB core logs an interface resume callback error.\nIt does not retry that callback, so a later callback cannot complete the\nskipped cleanup.\n\nusb_audio_suspend() increments num_suspended_intf before returning success.\nA system-resume callback must consume the system-suspend count even if a\ncomponent resume fails.
