From 6406c3d226374c28d452b11db3b5ac241ce26191 Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Mon, 12 Sep 2016 16:38:46 +0800 Subject: [PATCH] usb: Kconfig: let USB_ULPI_BUS depends on USB_COMMON Since ulpi bus driver is located at usb/common/ulpi.c, whether it is compiled or not depends on CONFIG_USB_COMMON which needs either USB Host or USB Gadget is enabled, so even CONFIG_USB_ULPI_BUS is chosen, its source may still not be compiled when both USB HOST and USB gadget are disabled. It fixed compile error with below configurations: - # CONFIG_USB is not set - # CONFIG_USB_GADGET is not set - CONFIG_PHY_TUSB1210=m - CONFIG_USB_ULPI_BUS=m >> All errors (new ones prefixed by >>): >> >> ERROR: "ulpi_unregister_driver" [drivers/phy/phy-tusb1210.ko] undefined! >> ERROR: "__ulpi_register_driver" [drivers/phy/phy-tusb1210.ko] undefined! >> ERROR: "ulpi_write" [drivers/phy/phy-tusb1210.ko] undefined!
