While the patch is correct I'd have something like this as well:

--- linux-2.6.11.orig/fs/sysfs/file.c
+++ linux-2.6.11/fs/sysfs/file.c
@@ -36,7 +36,7 @@ subsys_attr_store(struct kobject * kobj,
 {
        struct subsystem * s = to_subsys(kobj);
        struct subsys_attribute * sattr = to_sattr(attr);
-       ssize_t ret = 0;
+       ssize_t ret = -ENOSYS;
 
        if (sattr->store)
                ret = sattr->store(s,page,count);

So writes without store handler would return "not implemented".

(It is whitespace-mangled and therefore not a real patch - so no
signed-off-by...)
