Hi Greg,

After merging the usb tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

drivers/usb/core/port.c: In function 'usb_port_device_release':
drivers/usb/core/port.c:25:2: error: implicit declaration of function 'kfree' [-Werror=implicit-function-declaration]
drivers/usb/core/port.c: In function 'usb_hub_create_port_device':
drivers/usb/core/port.c:38:2: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration]
drivers/usb/core/port.c:38:11: warning: assignment makes pointer from integer without a cast [enabled by default]

Caused by commit 6e30d7cba992 ("usb: Add driver/usb/core/(port.c,hub.h)
files").  See Rule 1 in Documentation/SubmitChecklist.

I have used the usb tree from next-20130118 for today.
