Subject: [PATCH 24/25] skge: Adjust a null pointer check in skge_down()
Date: Mon, 17 Apr 2017 15:34:05 +0000 [thread overview]
Message-ID: <2122f892-68a6-e9cc-d15e-e82e62fc50b9@users.sourceforge.net> (raw)
In-Reply-To: <d6f26bba-c678-5b66-4f5d-85f56d895190@users.sourceforge.net>
From: Markus Elfring <elfring@users.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.
