Subject: [PATCH] gpio: Fix OF build problem on UM
Date: Tue, 16 Aug 2016 10:06:41 +0200	[thread overview]
Message-ID: <1471334801-2814-1-git-send-email-linus.walleij@linaro.org> (raw)

The UserMode (UM) Linux build was failing in gpiolib-of as it requires
ioremap()/iounmap() to exist, which is absent from UM. The non-existence
of IO memory is negatively defined as CONFIG_NO_IOMEM so put a reverse
dependency on !NO_IOMEM for OF_GPIO to fix the build.
