Well that's still not correct. The variable apd is compute by an upcast 
of the genpd parameter.

Since that upcast never returns a NULL value (gpd is not the first 
member of the structure) this whole check is completely nonsense.

I strongly suggest to just remove most of those NULL checks.

Only the ones directly after memory allocation really make sense.

Christian.

Will remove Null checks and post the new patch.
