Subject: [PATCH 2/3] AVR32: Delete an unnecessary variable initialisation in
 setup_rt_frame()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 18 Jan 2017 14:03:10 +0100

The local variable "err" will be set to an appropriate value a bit later.
Thus omit the explicit initialisation at the beginning.
