Subject: [PATCH 1/3] ath9k: Reduce function calls for sequence output in
 read_file_dma()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 8 May 2017 21:55:09 +0200

Some data were put into a sequence by separate function calls.
Print the same data with two function calls less.

This issue was detected by using the Coccinelle software.
