[PATCH 2/8] [media] v4l2-async: Delete an error message for a failed memory allocation in v4l2_async_notifier_unregister()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 26 Dec 2016 19:19:49 +0100

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

WARNING: Possible unnecessary 'out of memory' message

Thus fix the affected source code place.
