Subject: [PATCH 4/4] ASoC: twl4030: Delete an unnecessary variable
 initialisation in twl4030_get_pdata()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 23 Nov 2017 21:54:10 +0100

The variable "twl4030_codec_node" will be reassigned by
a following statement.
Thus omit the explicit initialisation at the beginning.
