The explicit typcasts are meaningless, so remove them.

Hi, Christian!

Since I introduced this patch and changed the TTM VM helper patch
enough to motivate removing your R-B, I wonder whether you could do a
quick review on these two and if OK also ack merging through vmwgfx?

Thanks,
Thomas

Hi Thomas,

this one and patch #3 are still Reviewed-by: Christian König 
<christian.koenig@amd.com>

Any objections that I cherry pick them over into our branch? Upstreaming 
that stuff got delayed quite a bit and I want to base a cleanup on this.

Thanks,
Christian.

Sure, please do. We can sort out any merge problems later. Let me
quickly fix the commit message of patch #3 since it doesn't reflect that
we export more helpers, and I'll send out these two as a separate patchset.

Thanks,
Thomas
