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.
