From 673550a19f01c7955a1321ed9f43a4e2fd9cabf6 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 27 May 2012 02:42:12 +0000 Subject: ARM: s3c24xx: fix multiple section mismatch warnings The *_irq_add function should not be marked __init because the driver subsystem thinks they might be called at a later stage. The usb_simtec_init function accesses initdata and should be marked init. This is safe because the only caller is also an init function. Without this patch, building s3c2410_defconfig results in: WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0x1030): Section mismatch in reference from the variable s3c2416_irq_interface to the function .init.text:s3c2416_irq_add() The variable s3c2416_irq_interface references the function __init s3c2416_irq_add() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0x1b08): Section mismatch in reference from the variable s3c2443_irq_interface to the function .init.text:s3c2443_irq_add() The variable s3c2443_irq_interface references the function __init s3c2443_irq_add() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0xf44): Section mismatch in reference from the variable s3c2416_irq_interface to the function .init.text:s3c2416_irq_add() The variable s3c2416_irq_interface references the function __init s3c2416_irq_add() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console WARNING: arch/arm/mach-s3c24xx/built-in.o(.text+0x3f7c): Section mismatch in reference from the function usb_simtec_init() to the (unknown reference) .init.data:(unknown) The function usb_simtec_init() references the (unknown reference) __initdata (unknown). This is often because usb_simtec_init lacks a __initdata annotation or the annotation of (unknown) is wrong.
