Date: Mon, 25 Mar 2019 14:54:30 +0100 From: Arnd Bergmann <arnd@...db.de> To: Chunfeng Yun <chunfeng.yun@...iatek.com>, Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Arnd Bergmann <arnd@...db.de>, Felipe Balbi <felipe.balbi@...ux.intel.com>, linux-usb@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-mediatek@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH] usb: mtu3: fix EXTCON dependency When EXTCON is a loadable module, mtu3 fails to link as built-in: drivers/usb/mtu3/mtu3_plat.o: In function `mtu3_probe': mtu3_plat.c:(.text+0x690): undefined reference to `extcon_get_edev_by_phandle' Add a Kconfig dependency to force mtu3 also to be a loadable module if extconn is, but still allow it to be built without extcon.
