Subject: [PATCH v2 02/10] staging: ks7010: Delete unnecessary assignments for
 buffer variables

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 10 Aug 2016 17:26:01 +0200

A few variables were assigned a null pointer despite of the detail
that they were immediately reassigned by the following statement.
Thus remove such unnecessary assignments.
