From 6a89a314ab107a12af08c71420c19a37a30fc2d3 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 18 Jan 2013 15:57:46 +0800 Subject: gpio: devm_gpio_* support should not depend on GPIOLIB Some architectures (e.g. blackfin) provide gpio API without requiring GPIOLIB support (ARCH_WANT_OPTIONAL_GPIOLIB). devm_gpio_* functions should also work for these architectures, since they do not really depend on GPIOLIB. Add a new option GPIO_DEVRES (enabled by default) to control the build of devres.c. It also removes the empty version of devm_gpio_* functions for !GENERIC_GPIO build from linux/gpio.h, and moves the function declarations from asm-generic/gpio.h into linux/gpio.h.
