Subject: [PATCH 1/4] net: stmmac: Combine three seq_printf() calls into a
 seq_puts() in stmmac_sysfs_dma_cap_read()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 9 May 2017 13:10:28 +0200

A bit of text was put into a sequence by three separate function calls.
Print the same data by a single function call instead.

This issue was detected by using the Coccinelle software.
