Subject: [PATCH 1/3] kernel-sched: Use seq_putc() in three functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 6 May 2017 20:45:35 +0200

Four single characters (line breaks) should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.
