Re: linux-next: build failure after merge of the amdgpu tree

Hi Alex,

Do we need to apply David's patch [1] to drm-misc-next? If so, I can merge it there. Also, I noticed that drm-misc-next changed the dp header path; in that way, I had to change the original patch a little bit.

1. https://patchwork.freedesktop.org/patch/480331/?series=102035&rev=1

Best Regards,
Siqueira

Subject: linux-next: build failure after merge of the amdgpu tree

Hi all,

After merging the amdgpu tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/amd/amdgpu/../display/modules/power/power_helpers.c: In function 'is_psr_su_specific_panel':
drivers/gpu/drm/amd/amdgpu/../display/modules/power/power_helpers.c:798:61: error: 'DP_PSR2_WITH_Y_COORD_ET_SUPPORTED' undeclared (first use in this function); did you mean 'DP_PSR2_WITH_Y_COORD_IS_SUPPORTED'?
   798 |                 if (link->dpcd_caps.psr_info.psr_version >= DP_PSR2_WITH_Y_COORD_ET_SUPPORTED)
       |                                                             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
       |                                                             DP_PSR2_WITH_Y_COORD_IS_SUPPORTED
drivers/gpu/drm/amd/amdgpu/../display/modules/power/power_helpers.c:798:61: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

   901029aa0017 ("drm/amd/display: implement shared PSR-SU sink validation helper")

Please start including an x86_64 allmodconfig build in your local testing.

I have used the amdgpu tree from next-20220412 for today.
