According to Documentation/filesystems/sysfs.txt:
show() methods of device attributes should return the number
of bytes printed into the buffer. This is the return value of
scnprintf(). snprintf() returns the length the resulting string.

So, show() should not use snprintf() when formatting
the value to be returned to user space.
Also, use sysfs_emit directly makes more sense.
