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

    USB: Add LPM quirk for Lenovo ThinkPad USB-C Dock Gen2 Ethernet

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-testing 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 be merged to the usb-next branch sometime soon,
after it passes testing, and the merge window is open.

If you have any questions about this process, please let me know.

Subject: USB: Add LPM quirk for Lenovo ThinkPad USB-C Dock Gen2 Ethernet

This is another branded 8153 device that doesn't work well with LPM
enabled:
[ 400.597506] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71

So disable LPM to resolve the issue.
