This is a note to let you know that I've just added the patch titled USB: cdc-acm: add device-id for quirky printer 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. >From fe855789d605590e57f9cd968d85ecce46f5c3fd Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan@xxxxxxxxxx> Date: Wed, 12 Jul 2017 15:08:39 +0200 Subject: USB: cdc-acm: add device-id for quirky printer Add device-id entry for DATECS FP-2000 fiscal printer needing the NO_UNION_NORMAL quirk.
