#1635198 — [PATCH 0/2] blk-mq-debugfs: Fine-tuning for five function implementations

From: Markus Elfring <elfring@users.sourceforge.net>

Two update suggestions were taken into account
from static source code analysis.

Markus Elfring (2):
  Replace seven seq_puts() calls by seq_putc()
  Add spaces in queue_poll_stat_show()

#1635201 — [PATCH 1/2] blk-mq-debugfs: Replace seven seq_puts() calls by seq_putc()

From: Markus Elfring <elfring@users.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.
