Hi,

First of all, thank you for your patch.

I just have one tiny comment inline.

This `if` condition only has one action, which means that you don't need
to add `{}` in the above statement. See:

https://www.kernel.org/doc/html/v4.10/process/coding-style.html#placing-braces-and-spaces

Thanks

Hi Melissa,

First of all, thank you very much for this patchset; in general,
everything looks good to me.

I noticed that your patchset does not apply because you made your
changes based on `drm-misc-next`; when you send patches to amdgpu, use
the following repository:

 git://people.freedesktop.org/~agd5f/linux 

Could you prepare a V2?

Thanks!
