#1637955 — [PATCH] wil6210: Replace five seq_puts() calls by seq_putc()

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 8 May 2017 22:22:04 +0200

Five single characters (line breaks) should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.

There is no _issue_ at all here, only a matter of taste.

printf("\n")  or putchar('\n')  in some slow path is really not that
interesting.
