Subject: [PATCH 1/2] [media] r820t: Delete an unnecessary variable
 initialisation in generic_set_freq()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 28 Dec 2015 16:36:44 +0100

The variable "rc" will be set to an appropriate value from a call of
the r820t_set_tv_standard() function.
Thus let us omit the explicit initialisation at the beginning.
