Replace sprintf() with sysfs_emit() in all sysfs attribute show functions. sysfs_emit() is aware of the sysfs buffer page size limit and should be used instead of sprintf() for sysfs show callbacks to prevent potential buffer overflows.

Also add the missing trailing newline to each output, which is the standard convention for sysfs attributes.
