[PATCH resend] xHCI: remove redundant parameter in giveback_first_trb()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Remove unused parameter *td in giveback_first_trb(), and replace the code
equivalent to giveback_first_trb() in xhci_queue_isoc_tx() with a call to
the actual function.
