Um, it looks like you already submitted the change before this review.
In case you're not aware, amd-staging-drm-next is set up to auto-submit
with out the gerrit code review and pre-submission test we have on
amd-kfd-staging. Do not push to amd-staging-drm-next unless you really
mean to submit your changes. Please apply the two fixes I pointed out
below in a separate patch.
Thanks,
Felix
