Subject: [PATCH 06/18] [media] RedRat3: Delete an unnecessary variable
 initialisation in redrat3_get_firmware_rev()

From: Markus Elfring <elfring@...rs.sourceforge.net>

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