| Subject: gpio: Fix OF build problem on UM |
| |
| From: Linus Walleij <linus.walleij@linaro.org> |
| |
| commit 2527ecc9195e9c66252af24c4689e8a67cd4ccb9 upstream. |
| |
| 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 which means we |
| need to depend on HAS_IOMEM. |
