Subject: Re: [PATCH] drivers: gpu: drm: amd: powerplay: hwmgr: Remove unused
 variable

Hi list,

I just wondered: I send the patch >14 days ago, 9 days ago it was 
reviewed by Rex Zhu. As far as I know, it isn't applied by now. At 
least I did not get a mail indicating that it was applied.

Are there issues with the patch I missed?
