According to Documentation/filesystems/sysfs.rst, the show() callback
function of kobject attributes should strictly use sysfs_emit() instead
of sprintf() family functions. So, make this change.
Also, change in length of lines enables code allows to reformat code for
improved readability.
Issue identified using the coccinelle device_attr_show.cocci script.
