Subject: [PATCH] iio/light: Delete an error message for a failed memory
 allocation in two functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 31 Jan 2018 21:12:09 +0100

Omit an extra message for a memory allocation failure in these functions.

This issue was detected by using the Coccinelle software.
