Hi Sameer,

[unrelated to this email: anything that comes from NVIDIA reaches me
 encrypted with my public key. Not a big deal, but it'd be good if
 someone could fix that.]

On its own, I'm not opposed to that patch.

But given that there is no in-tree platform using this, despite the code
sitting here for more than 2.5 years, this is just updating dead code.

Am I missing anything?

Thanks,
