From: Niklas Neronin <niklas.neronin@xxxxxxxxxxxxxxx>
Stall handling is managed in the 'process_*' functions, which are called
right before the 'goto' stall handling code snippet. Thus, there should
be a return after the 'process_*' functions. Otherwise, the stall code may
run twice.
Fixes: 1b349f214ac7 ("usb: xhci: add 'goto' for halted endpoint check in handle_tx_event()")
