+Subject: [PATCH] usb: chipidea: fix the build error with randconfig
+
+Using below  configs, the compile will have error:
+ERROR: "ehci_init_driver" undefined!
+
+.config:
+CONFIG_USB_CHIPIDEA=m
+CONFIG_USB_CHIPIDEA_HOST=y
+CONFIG_USB_CHIPIDEA_DEBUG=y
+
+The reason is chipidea host uses symbol from ehci, but ehci
+is not compiled. Let the chipidea host depend on
+ehci even it is built as module.
