Hi Felipe,

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

drivers/usb/phy/of.c:32:24: error: redefinition of 'of_usb_get_phy_mode'
 enum usb_phy_interface of_usb_get_phy_mode(struct device_node *np)
                        ^
In file included from drivers/usb/phy/of.c:13:0:
include/linux/usb/of.h:33:38: note: previous definition of 'of_usb_get_phy_mode' was here
 static inline enum usb_phy_interface of_usb_get_phy_mode(struct device_node *np)
                                      ^

Caused by commit 052a11d13bde ("usb: phy: make PHY driver selection
possible by controller drivers").  The static inline declaration in
include/linux/usb/of.h is exposed if at least one of CONFIG_OF or
CONFIG_USB_PHY is not set, but drivers/usb/phy/of.c is now built if
CONFIG_OF and CONFIG_USB_SUPPORT is set (it used to require
CONFIG_USB_PHY to be set - see drivers/usb/Makefile).  This build has
CONFIG_OF set but CONFIG_USB_PHY not set.

I have used the usb-gadget tree from next-20130729 for today.
