Thanks Christian, I'll improve the coding style.

Coding style: You can drop the "()",  but there should be spaces before
and after the "?" and ":".

And please double check that this change doesn't affect any other user
of amdgpu_bo_create_kernel()/amdgpu_bo_create_reserved().

Apart from that looks good to me and is a nice improvement,
Christian.
