[PATCH next-20140424] staging/cxt1e1: hwprobe.c sparse warning corrections

[Sami Laine <laine.j.sami@gmail.com>]

From: Sami Laine <laine.j.sami@gmail.com>

Sparse warning corrections:
 - declarations made static where they should be such
 - changed NULL-pointers as NULL instead of static 0's
 - added __force to a few casts seemingly safe enough
