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

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

[SF Markus Elfring]

From: Markus Elfring <elfring@users.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.

Sorry, i'm not happy with this patch. It doesn't increase readabilityand
mixes the output of multiple lines.

The only benefit is a little bit higher performance. But for debugfs
this won't be necessary.

I would prefer such a small code reduction. I am not so concerned
about an other readability impression at this place.

I would appreciate also another improvement there.
