While doing an investigation for a possible treewide conversion of
sysfs output using sprintf/snprintf/scnprintf, I discovered
several instances of sysfs output without terminating newlines.

It seems likely all of these should have newline terminations
or have the \n\r termination changed to a single newline.

Anyone have any objection to patches adding newlines to these
in their original forms using sprintf/snprintf/scnprintf?

A few of these might be false positives as
	"%s", string
might already have string with a newline termination.
