Fix compilation error when CONFIG_CPU_FREQ_S3C24XX_DEBUGFS selected.
Signed-off-by: Denis Kuzmenko <linux@xxxxxxxxxxxxxx>
---
Patch is against 3.2-rc4.
CONFIG_S3C2410_IOTIMING is not selected for MACH_MINI2440. Because of this the
file s3c2410-iotiming.c is not ever compiled and enabling
CONFIG_CPU_FREQ_S3C24XX_DEBUGFS option caused undefined reference to function
s3c2410_iotiming_debugfs defined in that file. s3c2410_iotiming_debugfs defined
as NULL for this case.
Changelog:
v1 -> v2
New CONFIG_ symbols S3C241{0,2}_IOTIMING were removed as It was observed that
they already present but hidden from user.
