[1825416995]

hello，uboot official website personnel. 
I am writing this email，is want to to ask you a question.
I have a little confused in usb dwc3 controller. in detail, when dwc3 controller as the device  peripheral , and in setup transfer: if the data stage have two trb, the first trb type is 'Control-Data', and the other trb type i think is 'Normal'. but in your code, the other trb is also 'Control-Data'. so I think this is a error.(in function "__dwc3_ep0_do_control_data" of file ep0.c )


I don't know if I understand this correct ly. attached is the corresponding code😊
