Subject: [PATCH 1/5] staging/lustre/llite: Use seq_puts() in three functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 1 Jan 2017 15:30:45 +0100

A string which did not contain a data format specification should be put
into a sequence. Thus use the corresponding function "seq_puts"
so that the data output will be a bit more efficient in these functions.

This issue was detected by using the Coccinelle software.
