Subject: linux-next: build failure after merge of the driver-core tree

Hi Greg,

After merging the driver-core tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: "devm_gpio_request_one" [drivers/extcon/extcon-arizona.ko] undefined!

Caused by commit 01eaf2458773 ("extcon: Convert extcon_gpio to
devm_gpio_request_one").  devm_gpio_request_one is not currently exported
to modules.

This has not been seen earlier because CONFIG_MFD_ARIZONA only got added
today :-(

I have added the following merge fix patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Tue, 10 Jul 2012 15:25:14 +1000
Subject: [PATCH] extcon: extcon-arizone can not be built as a module for now

fixes this build error:

ERROR: "devm_gpio_request_one" [drivers/extcon/extcon-arizona.ko] undefined!
