Subject: [PATCH 24/25] skge: Adjust a null pointer check in skge_down()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 17 Apr 2017 16:08:39 +0200

The script "checkpatch.pl" pointed information out like the following.

Comparison to NULL could be written "!skge->mem".

Thus fix the affected source code place.
