Subject: [PATCH 1/3] net/atm: Combine four seq_printf() calls in mpc_show()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 2 May 2017 18:52:58 +0200

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

This issue was detected by using the Coccinelle software.
