Subject: [PATCH] dwc_otg: initialise sched_frame for periodic QHs
|
|
that were parked
|
|
|
|
If a periodic QH has no remaining QTDs, then it is removed from all
|
|
periodic schedules. When re-adding, initialise the sched_frame and
|
|
start_split_frame from the current value of the frame counter.
|
|
|
