Subject[PATCH] net-procfs: Adjust buffer output in dev_mc_seq_show()
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 10 May 2017 21:17:43 +0200

* Use a special format string specification for the desired output of the
array "addr" into a sequence.

This issue was detected by using the Coccinelle software.

* Delete the local variable "i" and a call of the function "seq_putc"
which became unnecessary with this refactoring.
