Oleg, thank you for the patch, thoiugh it contains two issues, i.e.
- each new attribute in sysfs is ABI, *must* be documented; if there
is no such file present at all, you may start a new one;
- the commit message is formatted rather as in SVN style, in Git we
have a separate line for subject followed by empty line that followed
by body of commit message.
The code itself, assuming it's tested, looks good.
