   1 From: Peter Chen <peter.chen@freescale.com>
   2 Subject: [PATCH] usb: chipidea: fix the build error with randconfig
   3
   4 Using below  configs, the compile will have error:
   5 ERROR: "ehci_init_driver" undefined!
   6
   7 .config:
   8 CONFIG_USB_CHIPIDEA=m
   9 CONFIG_USB_CHIPIDEA_HOST=y
  10 CONFIG_USB_CHIPIDEA_DEBUG=y
  11
  12 The reason is chipidea host uses symbol from ehci, but ehci
  13 is not compiled. Let the chipidea host depend on
  14 ehci even it is built as module.
