[PATCH 6/6] [media] tda8261: Delete an unnecessary variable initialisation in three functions

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Tue, 26 Sep 2017 12:55:16 +0200

The local variable "err" is reassigned by a statement at the beginning.
Thus omit the explicit initialisation in these functions.
