[gregkh]

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

    usb: quirks: Add no-lpm quirk for Acer C120 LED Projector

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: quirks: Add no-lpm quirk for Acer C120 LED Projector

The Acer C120 LED Projector is a USB-3 connected pico projector which
takes both its power and video data from USB-3.

In combination with some hubs this device does not play well with
lpm, so disable lpm for it.
