+Hi,
+
+int sysfs_write_attribute(struct sysfs_attribute *sysattr,
+                const char *new_value, size_t len)
+
+has a problematic "feature": if the file is empty but readable, nothing gets
+written into it. The attached patch (untested) should fix it.
+
+	Dominik
+
+
+The check which tests whether the value to be written into a sysfs attribute
+is already there should only trigger if the length of both strings is the
+same.
