Subject: [RESEND PATCH] usb: mtu3: fix up undefined reference to usb_debug_root
Date: Fri, 24 May 2019 14:11:33 +0800	[thread overview]
Message-ID: <ee71197a681165aa72cb73c7f6cb402953351805.1558678075.git.chunfeng.yun@mediatek.com> (raw)

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.
