This is a note to let you know that I've just added the patch titled
qcserial: bind to DM/DIAG port on Gobi 1K devices
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: qcserial: bind to DM/DIAG port on Gobi 1K devices
Turns out we just need altsetting 1 and then we can talk to it.
