[PATCH] drm/amdkfd: Delete a useless parameter from create_queue function pointer

[Felix Kuehling]

Hi Oded,

Yong made this patch against our internal KFD branch. I asked him to
send it to upstream as well, since it applies to code I have already
upstreamed. I'm going to do this for more patches in the future as more
KFD code is upstream and more of our internal changes are applicable
upstream directly.

Is this OK with you, or do you prefer getting all patches through me, in
roughly bi-weekly batches as part of my on-going upstreaming effort?

Hi Yong,

Which branch is this patch against? For upstream KFD commits, they
should be applied against amdkfd-next on
git://people.freedesktop.org/~gabbayo/linux. Oded will apply the patch
if he accepts it, so you only need read access to this repository.

Also, please remove the Change-Id from the commit message. It is
meaningless for upstream submissions outside of our Gerrit server.

Other than that, this patch is Reviewed-by: Felix Kuehling <Felix

Regards,
  Felix
