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

Hi Greg,

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

drivers/net/usb/ipheth.c: In function 'ipheth_alloc_urbs':
drivers/net/usb/ipheth.c:131: error: implicit declaration of function 'usb_buffer_alloc'
drivers/net/usb/ipheth.c:134: warning: assignment makes pointer from integer without a cast
drivers/net/usb/ipheth.c:141: warning: assignment makes pointer from integer without a cast
drivers/net/usb/ipheth.c:153: error: implicit declaration of function 'usb_buffer_free'

Caused by commit 3cc96f50329227fbf34de2459491901b6ee1c98c ("USB: rename
usb_buffer_alloc() and usb_buffer_free() users") from the usb tree
interacting with commit a19259c3d589a014e5f47f148f74dfc44422c82b
("drivers/net/usb: Add new driver ipheth") which entered Linus' tree about
April 25 via the net tree.

I applied the following fixup patch for today.
