Andrew,
We're somehow new on this procedure. Are you referring to rebase this 
patch series to
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git 
<5.17-rc1 tag>?

Regards,
Alex Sierra

Alex Deucher,
Just a quick heads up. This patch series contains changes to the amdgpu 
driver which we're
planning to merge through Andrew's tree, If that's ok with you.

Regards,
Alex Sierra
