Pending.
But because the descriptors in the pendding list are only queued to cppi41
Likewise.
on runtime resume, the descriptor will not be queued. On runtime suspend, the list is not empty, which is causing a warning. Queue the descriptor if the device is active or resuming. Signed-off-by: Alexandre Bailon <abailon@xxxxxxxxxxxx>
