This is a note to let you know that I've just added the patch titled
USB: Add LPM quirk for Surface Dock GigE adapter
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: Add LPM quirk for Surface Dock GigE adapter
Without USB_QUIRK_NO_LPM ethernet will not work and rtl8152 will
complain with
r8152 <device...>: Stop submitting intr, status -71
Adding the quirk resolves this. As the dock is externally powered, this
should not have any drawbacks.
