From baaf939db44d08ef910558ff5eb16d123df3f621 Mon Sep 17 00:00:00 2001 From: Denis Kuzmenko Date: Wed, 28 Dec 2011 14:04:51 +0900 Subject: [PATCH 1/2] ARM: SAMSUNG: Fix build error when selecting CPU_FREQ_S3C24XX_DEBUGFS on S3C2440 Following is happened when CONFIG_CPU_FREQ_S3C24XX_DEBUGFS is selected without building of s3c2410-iotiming.c file: arch/arm/mach-s3c2440/built-in.o:(.data+0x38c): undefined reference to `s3c2410_iotiming_debugfs Basically, the CONFIG_S3C2410_IOTIMING is not selected for MACH_MINI2440. Because the s3c2410-iotiming.c is not ever compiled and enabling CONFIG_CPU_FREQ_S3C24XX_DEBUGFS option caused undefined reference to s3c2410_iotiming_debugfs() defined in that file. The s3c2410_iotiming_debugfs defined as NULL for this case.
