that throws

drivers/media/media-device.c: In function '__media_device_usb_init':
drivers/media/media-device.c:878:5: warning: "CONFIG_USB" is not defined 
[-Wundef]
 #if CONFIG_USB || (MODULE && CONFIG_USB_MODULE)
     ^

however, taking arch/arm/mach-omap1/include/mach/usb.h as example, 
changing it to 

--- a/drivers/media/media-device.c
+++ b/drivers/media/media-device.c
@@ -875,7 +875,7 @@ void __media_device_usb_init(struct medi
                             const char *board_name,
                             const char *driver_name)
 {
-#ifdef CONFIG_USB
+#if defined(CONFIG_USB) || defined(CONFIG_USB_MODULE)
        mdev->dev = &udev->dev;
 
        if (driver_name)

indeed fixes the problem for me

Thanks a lot!
