Message-ID<t7J6a-8py-5@gated-at.bofh.it>
Hi Greg,

After merging the tty tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

ERROR: "of_device_uevent_modalias" [drivers/tty/serdev/serdev.ko] undefined!
ERROR: "of_device_get_modalias" [drivers/tty/serdev/serdev.ko] undefined!

Caused by commit

  cd6484e1830b ("serdev: Introduce new bus for serial attached devices")

I have used the tty tree from next-20170203 for today.

Ugh, how has this been passing the 0-day bot builds succesfully?

Rob, any ideas?

It didn't, but we happened to already have a fix queued up for 4.11.
The fix is in your usb-next branch:

commit 7a3b7cd332db08546f3cdd984f11773e0d1999e7
Author: Stephen Boyd <stephen.boyd@linaro.org>
Date:   Wed Dec 28 14:56:48 2016 -0800

    of: device: Export of_device_{get_modalias, uvent_modalias} to modules

    The ULPI bus can be built as a module, and it will soon be
    calling these functions when it supports probing devices from DT.
    Export them so they can be used by the ULPI module.

Ah, so the if this is pulled into linux-next at the same time, then
there's no build error.

Stephen, do you need/want me to cherry-pick this into the tty branch, or
is it ok as-is?

thanks,

I will change things so that I merge the usb tree before the tty tree.
Please remember to tell Linus that they need to be merged in that order.
