Subject: [PATCH v2 12/17 2/4] mfd: tps65910: Delete an unnecessary variable
 initialisation in four functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 9 Mar 2018 09:06:14 +0100

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