Subject: [PATCH 2/4] MIPS/kernel/proc: Use seq_putc() in show_cpuinfo()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 24 Oct 2016 12:54:15 +0200

A few 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.
