Subject: patch "usb: xhci: Add XHCI_TRUST_TX_LENGTH for Renesas uPD720201" added to usb-linus
Date: Wed, 27 Dec 2017 15:26:03 +0100 [thread overview]
Message-ID: <1514384763192176@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
usb: xhci: Add XHCI_TRUST_TX_LENGTH for Renesas uPD720201
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: usb: xhci: Add XHCI_TRUST_TX_LENGTH for Renesas uPD720201
When plugging in a USB webcam I see the following message:
xhci_hcd 0000:04:00.0: WARN Successful completion on short TX: needs
XHCI_TRUST_TX_LENGTH quirk?
handle_tx_event: 913 callbacks suppressed
All is quiet again with this patch (and I've done a fair but of soak
testing with the camera since).
