From 312b00e510af60175b2935404a1927e6480e91e7 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 25 Jan 2013 14:14:29 +0000 Subject: [PATCH] pinctrl: exynos: don't mark probing functions as __init Functions called from a driver probe() method must not be marked __init, because they may get called after the init phase is done, when the device shows up late, or because of deferred probing. Without this patch, building exynos_defconfig results in multiple warnings like: WARNING: drivers/pinctrl/built-in.o(.text+0x51bc): Section mismatch in reference from the function exynos5440_pinctrl_probe() to the function .init.text:exynos5440_gpiolib_register() The function exynos5440_pinctrl_probe() references the function __init exynos5440_gpiolib_register(). This is often because exynos5440_pinctrl_probe lacks a __init annotation or the annotation of exynos5440_gpiolib_register is wrong.
