I think your patch is in violation of this from
Documentation/filesystems/sysfs.txt:

Attributes
~~~~~~~~~
...
Attributes should be ASCII text files, preferably with only one value
per file. It is noted that it may not be efficient to contain only one
value per file, so it is socially acceptable to express an array of
values of the same type.

Mixing types, expressing multiple lines of data, and doing fancy
formatting of data is heavily frowned upon. Doing these things may get
you publically humiliated and your code rewritten without notice.
