Subject: [PATCH v2 0/2] Fix ep command fail issue in dequeue
Date: Mon, 14 Feb 2022 20:08:51 +0900 [thread overview]
Message-ID: <1644836933-141376-1-git-send-email-dh10.jung@samsung.com> (raw)
In-Reply-To: CGME20220214111148epcas2p3fac143c7870c53ecadfb6b093fcf626b@epcas2p3.samsung.com
It always sets DWC3_EP_END_TRANSFER_PENDING in dwc3_stop_active_transfer
even if dwc3_send_gadget_ep_cmd fails. It can cause some problems like
skipping clear stall commmand or giveback from dequeue. It could cause
hung task if ENDTRANSFER command should not be completed. It seems
like HW(Controller) issue but SW can prevent it.
Changes in v2:
- fix coding rule
Daehwan Jung (2):
usb: dwc3: Not set DWC3_EP_END_TRANSFER_PENDING in ep cmd fails
usb: dwc3: Prevent cleanup cancelled requests at the same time.
