Date: Wed, 28 Jan 2015 22:47:18 +0100 From: Arnd Bergmann <arnd@...db.de> To: gregkh@...uxfoundation.org Cc: linux-usb@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, Felipe Balbi <balbi@...com>, Yoshihiro Shimoda <yoshihiro.shimoda.uh@...esas.com>, linux-kernel@...r.kernel.org Subject: [PATCH] usb: renesas: fix extcon dependency The renesas usbhs driver calls extcon_get_edev_by_phandle(), which is defined in drivers/extcon/extcon-class.c, and that can be a loadable module. If the extcon-class support is disabled, usbhs will work correctly for all devices that do not need extcon. However, if extcon-class is a loadable module, and usbhs is built-in, the kernel fails to link. In order to solve that, we need a Kconfig dependency that allows extcon to be disabled but does not allow usbhs built-in if extcon is a module.
