Subject: [PATCH] qca_debug: Reduce function calls for sequence output in
 qcaspi_info_show()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 8 May 2017 19:21:27 +0200

A bit of data was put into a sequence by separate function calls.
Print the same data together with adjusted seq_printf() calls instead.

This issue was detected by using the Coccinelle software.
