1 Hi,
2
3 int sysfs_write_attribute(struct sysfs_attribute *sysattr,
4                 const char *new_value, size_t len)
5
6 has a problematic "feature": if the file is empty but readable, nothing gets
7 written into it. The attached patch (untested) should fix it.

12 The check which tests whether the value to be written into a sysfs attribute
13 is already there should only trigger if the length of both strings is the
14 same.
