-Subject: [PATCH] MLK-19153-2 usb: host: xhci: do not return error status for
- URB
-
-Current XHCI implementation does not consider completion interrupt
-for SETUP packet standalone, so it will show warning message
-and return error status for URB. In fact, it can support it. In
-this commit, we change warning message as debug message and set
-status as zero for URB.
-
-Support completion interrupt for SETUP packet is needed for USB EH2.0
-SINGLE_STEP_SET_FEATURE Test.
