Subject: [PATCH 2/3] NFS: Replace 16 seq_printf() calls by seq_puts()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 3 Jul 2019 15:50:37 +0200

Some strings should be put into a sequence.
Thus use the corresponding function “seq_puts”.

This issue was detected by using the Coccinelle software.
