In dwc2_hcd_qh_deactivate() we will put some things on the periodic_sched_ready list. These things won't be taken off the ready list until the next SOF, which might be a little late. Let's put them on right away. Signed-off-by: Douglas Anderson <dianders@chromium.org> --- Changes in v4: - Schedule periodic right away if it's time new for v4.
