4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Corentin Labbe <clabbe.montjoie@gmail.com>
commit d2f48f05cd2a2a0a708fbfa45f1a00a87660d937 upstream.
When plugging an USB webcam I see the following message: [106385.615559] xhci_hcd 0000:04:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk? [106390.583860] handle_tx_event: 913 callbacks suppressed
With this patch applied, I get no more printing of this message.
