Tom Rix 08be5aadef video: fbdev: pvr2fb: initialize variables 
[ Upstream commit 8e1ba47c60bcd325fdd097cd76054639155e5d2e ]

clang static analysis reports this repesentative error

pvr2fb.c:1049:2: warning: 1st function call argument
  is an uninitialized value [core.CallAndMessage]
        if (*cable_arg)
        ^~~~~~~~~~~~~~~

Problem is that cable_arg depends on the input loop to
set the cable_arg[0].  If it does not, then some random
value from the stack is used.

A similar problem exists for output_arg.

So initialize cable_arg and output_arg.
