Subject: [PATCH 1/2] blk-mq-debugfs: Replace seven seq_puts() calls by
 seq_putc()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 3 May 2017 20:00:49 +0200

A few single characters should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.
