Arnd Bergmann b5a2a8ecb2 usbip: vudc: fix Kconfig dependencies
With the addition of VUDC, the USBIP stack can now be used on
configurations without USB host support, but trying to build
it with USB gadget support disabled fails with

drivers/usb/built-in.o: In function `vep_dequeue':
vudc_main.c:(.text+0xa6ddc): undefined reference to `usb_gadget_giveback_request'
drivers/usb/built-in.o: In function `nuke':
vudc_main.c:(.text+0xa6ea8): undefined reference to `usb_gadget_giveback_request'
drivers/usb/built-in.o: In function `vudc_device_reset':
vudc_main.c:(.text+0xa720c): undefined reference to `usb_gadget_udc_reset'
drivers/usb/built-in.o: In function `vudc_probe':

This addresses both issues, by changing the dependency for USBIP_CORE
to USB_COMMON, and adding additional dependencies on USB or USB_GADGET
for the individual portions as needed.

config USBIP_CORE
tristate "USB/IP support"
depends on USB_COMMON && NET
---help---
This enables pushing USB packets over IP to allow remote
machines direct access to USB devices. It provides the
USB/IP core that is required by both drivers.
For more details, and to get the userspace utility
programs, please see <http://usbip.sourceforge.net/>.
To compile this as a module, choose M here: the module will
be called usbip-core.
If unsure, say N.
config USBIP_VHCI_HCD
tristate "VHCI hcd"
depends on USBIP_CORE && USB
---help---
This enables the USB/IP virtual host controller driver,
which is run on the remote machine.
To compile this driver as a module, choose M here: the
module will be called vhci-hcd.
config USBIP_HOST
tristate "Host driver"
depends on USBIP_CORE && USB
---help---
This enables the USB/IP host driver, which is run on the
machine that is sharing the USB devices.
To compile this driver as a module, choose M here: the
module will be called usbip-host.
config USBIP_VUDC
tristate "VUDC driver"
depends on USBIP_CORE && USB_GADGET
---help---
This enables the USB/IP virtual USB device controller
driver, which is run on the host machine, allowing the
machine itself to act as a device.
To compile this driver as a module, choose M here: the
module will be called usbip-vudc.
config USBIP_DEBUG
bool "Debug messages for USB/IP"
depends on USBIP_CORE
---help---
This enables the debug messages from the USB/IP drivers.
