[next PATCH] usb: mtu3: fix up undefined reference to usb_debug_root

From: Chunfeng Yun
Date: Sun May 05 2019 - 02:03:43 EST


When CONFIG_USB is not set, and CONFIG_USB_GADGET is set,
there is an issue:

ld:
drivers/usb/mtu3/mtu3_debugfs.o: in function 'ssusb_debugfs_create_root':
mtu3_debugfs.c:(.text+0xba3): undefined reference to 'usb_debug_root'

usb_debug_root is only built when CONFIG_USB is enabled, so here drop it
and use NULL instead.
