Patch from Ben Dooks If CONFIG_CPU_DCACHE_WRITETHOUGH is set, then the S3C24XX PM code fails to compile, as there is no need to flush the D-cache, the flush function arm920_flush_kern_cache_all() is not compiled. Fix the code to not use this if the config is set. Signed-off-by: NBen Dooks <ben-linux@fluff.org> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
