Subject: [PATCH 2/6] md: Replace 17 seq_printf() calls by seq_puts()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 2 May 2017 14:22:45 +0200

Strings which did not contain data format specifications should be put
into a sequence. Thus use the corresponding function "seq_puts".

This issue was detected by using the Coccinelle software.
