This driver uses the extcon subsystem and fails to build
when it cannot call into that subsystem:
x86_64-linux-ld: vmlinux.o: in function `yt2_1380_fc_worker':
lenovo-yoga-tab2-pro-1380-fastcharger.c:(.text+0xa9d819): undefined reference to `extcon_get_state'
x86_64-linux-ld: lenovo-yoga-tab2-pro-1380-fastcharger.c:(.text+0xa9d853): undefined reference to `extcon_get_state'
x86_64-linux-ld: vmlinux.o: in function `yt2_1380_fc_serdev_probe':
lenovo-yoga-tab2-pro-1380-fastcharger.c:(.text+0xa9da22): undefined reference to `extcon_get_extcon_dev'
x86_64-linux-ld: lenovo-yoga-tab2-pro-1380-fastcharger.c:(.text+0xa9dc0c): undefined reference to `devm_extcon_register_notifier_all'
Add a Kconfig dependency to make it it always builds correctly.

Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
I will include this patch in my next fixes pull-req to Linus
for the current kernel development cycle.
Regards,
Hans
