2017-07-30usb: mtu3: handle delayed status of the control transferChunfeng Yun3-3/+24
Add the delayed status handling. This is used by mass storage etc to gain some extra time to setup its internal status before it can proceed further requests, and once the gadget is ready, it will enqueue an empty packet which is used for synchronization. The issue may happen on some FGPA platform with very low cpu frequency. Signed-off-by: Chunfeng Yun <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
