Subject: [PATCH 06/34] [media] DaVinci-VPBE: Return an error code only by a
 single variable in vpbe_initialize()

An error code was assigned to the local variable "err" in an if branch.
But this variable was not used further then.

Use the local variable "ret" instead like at other places in this function.
