Since snprintf() has the documented, but still rather strange trait of returning the length of the data that *would have been* written to the array if space were available, rather than the arguably more useful length of data *actually* written, it is usually considered wise to use something else instead in order to avoid confusion. In the case of sysfs call-backs, new wrappers exist that do just that. This patch replaces the 2 uses of snprintf() found in the sysfs .show() call-backs with the new sysfs_emit() helpers. Whist we're at it, let's replace the sprintf()s as well. For no other reason than consistency.
