Subject: linux-next: build failure after merge of the usb-gadget tree

Hi Felipe,

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

Caused by commit e4f8ef7b0770 ("usb: gadget: nokia: Add mass storage
driver to g_nokia").

I have used the usb-gadget tree from next-20150528 for today.
