[PATCH 4.14 094/107] usb: mtu3: fix EXTCON dependency

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@xxxxxxxx>

commit 3d54d10c6afed34fd45b852bf76f55e8da31d8ef upstream.

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.

Fixes: d0ed062a8b75 ("usb: mtu3: dual-role mode support")
