[ARM] 3551/1: S3C24XX: PM code failes to compile with CONFIG_DCACHE_WRITETHROUGH
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: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
