Subject: [PATCH] staging: media: stkwebcam: add USB dependency

From: Arnd Bergmann <arnd@...db.de>

Before the move, this driver had implicit dependencies on both
CONFIG_USB and MEDIA_SUPPORT, which can be =m even in combination
with CONFIG_MEDIA_USB_SUPPORT=y, so without the dependency we
get a link failure when USB is a loadable module but stkwebcam
is built-in:

arm-linux-gnueabi-ld: drivers/staging/media/deprecated/stkwebcam/stk-webcam.o: in function `stk_camera_probe':
stk-webcam.c:(.text+0xcbc): undefined reference to `usb_get_dev'
arm-linux-gnueabi-ld: stk-webcam.c:(.text+0xccc): undefined reference to `usb_get_intf'
arm-linux-gnueabi-ld: stk-webcam.c:(.text+0xd68): undefined reference to `usb_put_intf'
arm-linux-gnueabi-ld: stk-webcam.c:(.text+0xd70): undefined reference to `usb_put_dev'
arm-linux-gnueabi-ld: drivers/staging/media/deprecated/stkwebcam/stk-webcam.o: in function `stk_prepare_iso':
stk-webcam.c:(.text+0xfcc): undefined reference to `usb_free_urb'
arm-linux-gnueabi-ld: stk-webcam.c:(.text+0x1010): undefined reference to `usb_alloc_urb'
arm-linux-gnueabi-ld: stk-webcam.c:(.text+0x10d8): undefined reference to `usb_kill_urb'

Add back the original dependency.
