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

USB: NO_LPM quirk Lenovo Powered USB-C Travel Hub

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: NO_LPM quirk Lenovo Powered USB-C Travel Hub

This is another branded 8153 device that doesn't work well with LPM:
r8152 2-2.1:1.0 enp0s13f0u2u1: Stop submitting intr, status -71

Disable LPM to resolve the issue.
