Subject: [PATCH 7/8] [media] cx231xx: Delete an unnecessary variable
 initialisation in read_eeprom()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 17 Sep 2017 20:28:00 +0200

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