   4 Subject: [PATCH] usb: chipidea: fix the build error with randconfig
   5
   6 Using below  configs, the compile will have error:
   7 ERROR: "ehci_init_driver" undefined!
   8
   9 .config:
  10 CONFIG_USB_CHIPIDEA=m
  11 CONFIG_USB_CHIPIDEA_HOST=y
  12 CONFIG_USB_CHIPIDEA_DEBUG=y
  13
  14 The reason is chipidea host uses symbol from ehci, but ehci
  15 is not compiled. Let the chipidea host depend on
  16 ehci even it is built as module.
