patch "usb: xhci: ASMedia ASM1042A chipset need shorts TX quirk" added to usb-linus

This is a note to let you know that I've just added the patch titled

usb: xhci: ASMedia ASM1042A chipset need shorts TX quirk

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.

Subject: usb: xhci: ASMedia ASM1042A chipset need shorts TX quirk

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.
