[Intel-gfx] [PATCH 2/2] drm/i915: make sparse happy for the new vlv mmio read function

[Daniel Vetter]

It doesn't like that we assign 0 to a pointer, it wants the real NULL.

On closer look that initialization is actually bogus, and the compiler
can easily see that we never use it unitialized. So let's just drop
this.
