USB: EHCI: defer reclamation of siTDs
This patch (as1369) fixes a problem in ehci-hcd. Some controllers occasionally run into trouble when the driver reclaims siTDs too quickly. This can happen while streaming audio; it causes the controller to crash. The patch changes siTD reclamation to work the same way as iTD reclamation: Completed siTDs are stored on a list and not reused until at least one frame has passed.
